One of the three gateways to liberation.

One of the three gateways to liberation.

In a general sense, samādhi can describe a number of different meditative states. In the Mahāyāna literature, in particular in the Prajñāpāramitā sūtras, we find extensive lists of different samādhis, numbering over one hundred.In a more restricted sense, and when understood as a mental state, samādhi is defined as the one-pointedness of the mind (cittaikāgratā), the ability to remain on the same object over long periods of time. The Drajor Bamponyipa (sgra sbyor bam po gnyis pa) commentary on the Mahāvyutpatti explains the term samādhi as referring to the instrument through which mind and mental states “get collected,” i.e., it is by the force of samādhi that the continuum of mind and mental states becomes collected on a single point of reference without getting distracted.

The essentially pure nature of mind is obscured and afflicted by various psychological defilements, which destroy the mind’s peace and composure and lead to unwholesome deeds of body, speech, and mind, acting as causes for continued existence in saṃsāra. Included among them are the primary afflictions of desire (rāga), anger (dveṣa), and ignorance (avidyā). It is said that there are eighty-four thousand of these negative mental qualities, for which the eighty-four thousand categories of the Buddha’s teachings serve as the antidote. Kleśa is also commonly translated as “negative emotions,” “disturbing emotions,” and so on. The Pāli kilesa, Middle Indic kileśa, and Buddhist Hybrid Sanskrit kleśa all primarily mean “stain” or “defilement.” The translation “affliction” is a secondary development that derives from the more general (non-Buddhist) classical understanding of √kliś (“to harm,“ “to afflict”). Both meanings are noted by Buddhist commentators.

Five collections of similar phenomena under which all compounded dharmas may be included: form, feeling, perception, formation, and consciousness. On the individual level the five aggregates refer to the basis upon which the mistaken idea of a self is projected.

The first monk that the Buddha Śākyamuni recognized as having understood his teachings.

A major śrāvaka disciple and personal attendant of the Buddha Śākyamuni during the last twenty-five years of his life. He was a cousin of the Buddha (according to the Mahāvastu, he was a son of Śuklodana, one of the brothers of King Śuddhodana, which means he was a brother of Devadatta; other sources say he was a son of Amṛtodana, another brother of King Śuddhodana, which means he would have been a brother of Aniruddha).Ānanda, having always been in the Buddha’s presence, is said to have memorized all the teachings he heard and is celebrated for having recited all the Buddha’s teachings by memory at the first council of the Buddhist saṅgha, thus preserving the teachings after the Buddha’s parinirvāṇa. The phrase “Thus did I hear at one time,” found at the beginning of the sūtras, usually stands for his recitation of the teachings. He became a patriarch after the passing of Mahākāśyapa.

A king of the nāgas.

Four types of mindfulness that regard the body, feelings, the mind, and dharmas.

A type of nonhuman being whose precise status is subject to different views, but is included as one of the six classes of beings in the sixfold classification of realms of rebirth. In the Buddhist context, asuras are powerful beings said to be dominated by envy, ambition, and hostility. They are also known in the pre-Buddhist and pre-Vedic mythologies of India and Iran, and feature prominently in Vedic and post-Vedic Brahmanical mythology, as well as in the Buddhist tradition. In these traditions, asuras are often described as being engaged in interminable conflict with the devas (gods).

Determination, discernment, diligence, and concentration.

A high-ranking deity presiding over a divine world; he is also considered to be the lord of the Sahā world (our universe). Though not considered a creator god in Buddhism, Brahmā occupies an important place as one of two gods (the other being Indra/Śakra) said to have first exhorted the Buddha Śākyamuni to teach the Dharma. The particular heavens found in the form realm over which Brahmā rules are often some of the most sought-after realms of higher rebirth in Buddhist literature. Since there are many universes or world systems, there are also multiple Brahmās presiding over them. His most frequent epithets are “Lord of the Sahā World” (sahāṃpati) and Great Brahmā (mahābrahman).

First god realm of form, it is the lowest of the three heavens that make up the first dhyāna heaven in the form realm.

A bodhisattva, the principal interlocutor of the Buddha in The Teaching on the Effulgence of Light.

Dhyāna is defined as one-pointed abiding in an undistracted state of mind, free from afflicted mental states. Four states of dhyāna are identified as being conducive to birth within the form realm. In the context of the Mahāyāna, it is the fifth of the six perfections. It is commonly translated as “concentration,” “meditative concentration,” and so on.

A king of the past.

The term dhāraṇī has the sense of something that “holds” or “retains,” and so it can refer to the special capacity of practitioners to memorize and recall detailed teachings. It can also refer to a verbal expression of the teachings‍—an incantation, spell, or mnemonic formula‍—that distills and “holds” essential points of the Dharma and is used by practitioners to attain mundane and supramundane goals. The same term is also used to denote texts that contain such formulas.

One of the Four Great Kings, he presides over the eastern quarter and rules over the gandharvas.

A buddha who preceded Śākyamuni and prophesied his awakening.

Correct view, intention, speech, actions, livelihood, effort, mindfulness, and concentration.

In the context of Buddhist philosophy, one way to describe experience in terms of eighteen elements (eye, form, and eye consciousness; ear, sound, and ear consciousness; nose, smell, and nose consciousness; tongue, taste, and tongue consciousness; body, touch, and body consciousness; and mind, mental phenomena, and mind consciousness).This also refers to the elements of the world, which can be enumerated as four, five, or six. The four elements are earth, water, fire, and air. A fifth, space, is often added, and the sixth is consciousness.

Emptiness denotes the ultimate nature of reality, the total absence of inherent existence and self-identity with respect to all phenomena. According to this view, all things and events are devoid of any independent, intrinsic reality that constitutes their essence. Nothing can be said to exist independent of the complex network of factors that gives rise to its origination, nor are phenomena independent of the cognitive processes and mental constructs that make up the conventional framework within which their identity and existence are posited. When all levels of conceptualization dissolve and when all forms of dichotomizing tendencies are quelled through deliberate meditative deconstruction of conceptual elaborations, the ultimate nature of reality will finally become manifest. It is the first of the three gateways to liberation.

A buddha of the past.

Four types of exertion of abandoning existing negative mind states, abandoning the production of such states, giving rise to virtuous mind states that are not yet produced, and letting those states continue.

Mindfulness, discrimination, diligence, joy, ease, absorption, and equanimity.

Four unique types of confidence possessed by a buddha, these are enumerated in a variety of ways.

Four levels of concentration conducive to birth within the form realm.

The four correct and unhindered discriminating knowledges of the doctrine or Dharma, of meaning, of language, and of brilliance or eloquence. These are the essential means by which the buddhas impart their teachings.

Generosity, kind words, meaningful actions, and practicing what one preaches.

Monks, nuns, and male and female lay practitioners.

The Buddha’s first teaching, which explains suffering, the origin of suffering, the cessation of suffering, and the path to the cessation of suffering.

A king of the nāgas.

A class of generally benevolent nonhuman beings who inhabit the skies, sometimes said to inhabit fantastic cities in the clouds, and more specifically to dwell on the eastern slopes of Mount Meru, where they are ruled by the Great King Dhṛtarāṣṭra. They are most renowned as celestial musicians who serve the gods. In the Abhidharma, the term is also used to refer to the mental body assumed by sentient beings during the intermediate state between death and rebirth. Gandharvas are said to live on fragrances (gandha) in the desire realm, hence the Tibetan translation dri za, meaning “scent eater.”

The Gaṅgā, or Ganges in English, is considered to be the most sacred river of India, particularly within the Hindu tradition. It starts in the Himalayas, flows through the northern plains of India, bathing the holy city of Vārāṇasī, and meets the sea at the Bay of Bengal, in Bangladesh. In the sūtras, however, this river is mostly mentioned not for its sacredness but for its abundant sands‍—noticeable still today on its many sandy banks and at its delta‍—which serve as a common metaphor for infinitely large numbers.According to Buddhist cosmology, as explained in the Abhidharmakośa, it is one of the four rivers that flow from Lake Anavatapta and cross the southern continent of Jambudvīpa‍—the known human world or more specifically the Indian subcontinent.

In Indian mythology, the garuḍa is an eagle-like bird that is regarded as the king of all birds, normally depicted with a sharp, owl-like beak, often holding a snake, and with large and powerful wings. They are traditionally enemies of the nāgas. In the Vedas, they are said to have brought nectar from the heavens to earth. Garuḍa can also be used as a proper name for a king of such creatures.

The Sanskrit term śrāvaka, and the Tibetan nyan thos, both derived from the verb “to hear,” are usually defined as “those who hear the teaching from the Buddha and make it heard to others.” Primarily this refers to those disciples of the Buddha who aspire to attain the state of an arhat seeking their own liberation and nirvāṇa. They are the practitioners of the first turning of the wheel of the Dharma on the four noble truths, who realize the suffering inherent in saṃsāra and focus on understanding that there is no independent self. By conquering afflicted mental states (kleśa), they liberate themselves, attaining first the stage of stream enterers at the path of seeing, followed by the stage of once-returners who will be reborn only one more time, and then the stage of non-returners who will no longer be reborn into the desire realm. The final goal is to become an arhat. These four stages are also known as the “four results of spiritual practice.”

One of the six heavens of the desire realm.

One of the six heavens of the desire realm.

Tuṣita (or sometimes Saṃtuṣita), literally “Joyous” or “Contented,” is one of the six heavens of the desire realm (kāmadhātu). In standard classifications, such as the one in the Abhidharmakośa, it is ranked as the fourth of the six counting from below. This god realm is where all future buddhas are said to dwell before taking on their final rebirth prior to awakening. There, the Buddha Śākyamuni lived his preceding life as the bodhisattva Śvetaketu. When departing to take birth in this world, he appointed the bodhisattva Maitreya, who will be the next buddha of this eon, as his Dharma regent in Tuṣita. For an account of the Buddha’s previous life in Tuṣita, see The Play in Full (Toh 95), 2.12, and for an account of Maitreya’s birth in Tuṣita and a description of this realm, see The Sūtra on Maitreya’s Birth in the Heaven of Joy , (Toh 199).

One of the six heavens of the desire realm.

One of the heavens of Buddhist cosmology, lowest among the six heavens of the desire realm (kāmadhātu, ’dod khams). Dwelling place of the Four Great Kings (caturmahārāja, rgyal chen bzhi), traditionally located on a terrace of Sumeru, just below the Heaven of the Thirty-Three. Each cardinal direction is ruled by one of the Four Great Kings and inhabited by a different class of nonhuman beings as their subjects: in the east, Dhṛtarāṣṭra rules the gandharvas; in the south, Virūḍhaka rules the kumbhāṇḍas; in the west, Virūpākṣa rules the nāgas; and in the north, Vaiśravaṇa rules the yakṣas.

One of the six heavens of the desire realm.

One of the eight hot hells.

A type of extrasensory perception gained through spiritual practice, in the Buddhist presentation consisting of five types: (1) miraculous abilities, (2) divine eye, (3) divine ear, (4) knowledge of others’ minds, and (5) recollection of past lives.

The name of the southern continent in Buddhist cosmology, which can signify either the known human world, or more specifically the Indian subcontinent, literally “the jambu island/continent.” Jambu is the name used for a range of plum-like fruits from trees belonging to the genus Szygium, particularly Szygium jambos and Szygium cumini, and it has commonly been rendered “rose apple,” although “black plum” may be a less misleading term. Among various explanations given for the continent being so named, one (in the Abhidharmakośa) is that a jambu tree grows in its northern mountains beside Lake Anavatapta, mythically considered the source of the four great rivers of India, and that the continent is therefore named from the tree or the fruit. Jambudvīpa has the Vajrāsana at its center and is the only continent upon which buddhas attain awakening.

One of the principal disciples of the Buddha Śākyamuni.

One of the principal disciples of the Buddha Śākyamuni.

A class of malevolent nonhuman beings who are often identified as the source of illness.

A short form of the name Candraprabhakumārabhūta.

A class of dwarf beings subordinate to Virūḍhaka, one of the Four Great Kings, associated with the southern direction. The name uses a play on the word aṇḍa, which means “egg” but is also a euphemism for a testicle. Thus, they are often depicted as having testicles as big as pots (from kumbha, or “pot”).

A senior student of the Buddha Śākyamuni, famous for his austere lifestyle.

Literally “great serpents,” mahoragas are supernatural beings depicted as large, subterranean beings with human torsos and heads and the lower bodies of serpents. Their movements are said to cause earthquakes, and they make up a class of subterranean geomantic spirits whose movement through the seasons and months of the year is deemed significant for construction projects.

The bodhisattva Maitreya is an important figure in many Buddhist traditions, where he is unanimously regarded as the buddha of the future era. He is said to currently reside in the heaven of Tuṣita, as Śākyamuni’s regent, where he awaits the proper time to take his final rebirth and become the fifth buddha in the Fortunate Eon, reestablishing the Dharma in this world after the teachings of the current buddha have disappeared. Within the Mahāyāna sūtras, Maitreya is elevated to the same status as other central bodhisattvas such as Mañjuśrī and Avalokiteśvara, and his name appears frequently in sūtras, either as the Buddha’s interlocutor or as a teacher of the Dharma. Maitreya literally means “Loving One.” He is also known as Ajita, meaning “Invincible.”For more information on Maitreya, see, for example, the introduction to Maitreya’s Setting Out (Toh 198).

A king of the nāgas.

Mañjuśrī is one of the “eight close sons of the Buddha” and a bodhisattva who embodies wisdom. He is a major figure in the Mahāyāna sūtras, appearing often as an interlocutor of the Buddha. In his most well-known iconographic form, he is portrayed bearing the sword of wisdom in his right hand and a volume of the Prajñā­pāramitā­sūtra in his left. To his name, Mañjuśrī, meaning “Gentle and Glorious One,” is often added the epithet Kumārabhūta, “having a youthful form.” He is also called Mañjughoṣa, Mañjusvara, and Pañcaśikha.

Māra, literally “death” or “maker of death,” is the name of the deva who tried to prevent the Buddha from achieving awakening, the name given to the class of beings he leads, and also an impersonal term for the destructive forces that keep beings imprisoned in saṃsāra: (1) As a deva, Māra is said to be the principal deity in the Heaven of Making Use of Others’ Emanations (paranirmitavaśavartin), the highest paradise in the desire realm. He famously attempted to prevent the Buddha’s awakening under the Bodhi tree‍—see The Play in Full (Toh 95), 21.1‍—and later sought many times to thwart the Buddha’s activity. In the sūtras, he often also creates obstacles to the progress of śrāvakas and bodhisattvas. (2) The devas ruled over by Māra are collectively called mārakāyika or mārakāyikadevatā, the “deities of Māra’s family or class.” In general, these māras too do not wish any being to escape from saṃsāra, but can also change their ways and even end up developing faith in the Buddha, as exemplified by Sārthavāha; see The Play in Full (Toh 95), 21.14 and 21.43. (3) The term māra can also be understood as personifying four defects that prevent awakening, called (i) the divine māra (devaputra­māra), which is the distraction of pleasures; (ii) the māra of Death (mṛtyumāra), which is having one’s life interrupted; (iii) the māra of the aggregates (skandhamāra), which is identifying with the five aggregates; and (iv) the māra of the afflictions (kleśamāra), which is being under the sway of the negative emotions of desire, hatred, and ignorance.

One of the principal śrāvaka disciples of the Buddha, paired with Śāriputra. He was renowned for his miraculous powers. His family clan was descended from Mudgala, hence his name Maudgalyā­yana, “the son of Mudgala’s descendants.” Respectfully referred to as Mahā­maudgalyā­yana, “Great Maudgalyāyana.”

A class of nonhuman beings who live in subterranean aquatic environments, where they guard wealth and sometimes also teachings. Nāgas are associated with serpents and have a snakelike appearance. In Buddhist art and in written accounts, they are regularly portrayed as half human and half snake, and they are also said to have the ability to change into human form. Some nāgas are Dharma protectors, but they can also bring retribution if they are disturbed. They may likewise fight one another, wage war, and destroy the lands of others by causing lightning, hail, and flooding.

A follower of one of the non-Buddhist religious systems in India.

The highest possible state in saṃsāra, it refers to the highest sphere of the formless realm, the Sphere of Neither Perception nor Nonperception.

When five, they are faith, diligence, mindfulness, absorption, and knowledge. These are the same as the five strengths. When listed as ten they refer to ten clairvoyant knowledges of a buddha: (1) the knowledge of what is possible and impossible, (2) the knowledge of the ripening of karma, (3) the knowledge of the variety of aspirations, (4) the knowledge of the variety of natures, (5) the knowledge of the different capabilities, (6) the knowledge of the destinations of all paths, (7) the knowledge of various states of meditation (concentration, liberation, absorption, etc.), (8) the knowledge of remembering previous lives, (9) the knowledge of deaths and rebirths, and (10) the knowledge of the cessation of defilements.

Absorptions that precede the achievement of the eight absorptions of the form and formless realms.

A powerful asura, said to cause eclipses.

The ancient capital of Magadha prior to its relocation to Pāṭaliputra during the Mauryan dynasty, Rājagṛha is one of the most important locations in Buddhist history. The literature tells us that the Buddha and his saṅgha spent a considerable amount of time in residence in and around Rājagṛha‍—in nearby places, such as the Vulture Peak Mountain (Gṛdhrakūṭaparvata), a major site of the Mahāyāna sūtras, and the Bamboo Grove (Veṇuvana)‍—enjoying the patronage of King Bimbisāra and then of his son King Ajātaśatru. Rājagṛha is also remembered as the location where the first Buddhist monastic council was held after the Buddha Śākyamuni passed into parinirvāṇa. Now known as Rajgir and located in the modern Indian state of Bihar.

A class of nonhuman beings that are often, but certainly not always, considered demonic in the Buddhist tradition. They are often depicted as flesh-eating monsters who haunt frightening places and are ugly and evil-natured with a yearning for human flesh, and who additionally have miraculous powers, such as being able to change their appearance.

The lord of the gods in the Heaven of the Thirty-Three (trāyastriṃśa). Alternatively known as Indra, the deity that is called “lord of the gods” dwells on the summit of Mount Sumeru and wields the thunderbolt. The Tibetan translation brgya byin (meaning “one hundred sacrifices”) is based on an etymology that śakra is an abbreviation of śata-kratu, one who has performed a hundred sacrifices. Each world with a central Sumeru has a Śakra. Also known by other names such as Kauśika, Devendra, and Śacipati.

An epithet for the historical Buddha, Siddhārtha Gautama: he was a muni (“sage”) from the Śākya clan. He is counted as the fourth of the first four buddhas of the present Good Eon, the other three being Krakucchanda, Kanakamuni, and Kāśyapa. He will be followed by Maitreya, the next buddha in this eon.

A god.

One of the principal śrāvaka disciples of the Buddha, he was renowned for his discipline and for having been praised by the Buddha as foremost of the wise (often paired with Maudgalyā­yana, who was praised as foremost in the capacity for miraculous powers). His father, Tiṣya, to honor Śāriputra’s mother, Śārikā, named him Śāradvatīputra, or, in its contracted form, Śāriputra, meaning “Śārikā’s Son.”

These can be listed as twelve or as six sense sources (sometimes also called sense fields, bases of cognition, or simply āyatanas).In the context of epistemology, it is one way of describing experience and the world in terms of twelve sense sources, which can be divided into inner and outer sense sources, namely: (1–2) eye and form, (3–4) ear and sound, (5–6) nose and odor, (7–8) tongue and taste, (9–10) body and touch, (11–12) mind and mental phenomena.In the context of the twelve links of dependent origination, only six sense sources are mentioned, and they are the inner sense sources (identical to the six faculties) of eye, ear, nose, tongue, body, and mind.

The six modes of supernormal cognition or ability, namely, clairvoyance, clairaudience, knowledge of the minds of others, remembrance of past lives, the ability to perform miracles, and the knowledge of the destruction of all mental defilements. The first five are considered mundane or worldly and can be attained to some extent by non-Buddhist yogis as well as Buddhist arhats and bodhisattvas. The sixth is considered to be supramundane and can be attained only by Buddhist yogis.

The trainings of the bodhisattva path: generosity, discipline, patience, diligence, concentration, and insight.

Literally, “buddha for oneself” or “solitary realizer.” Someone who, in his or her last life, attains awakening entirely through their own contemplation, without relying on a teacher. Unlike the awakening of a fully realized buddha (samyaksambuddha), the accomplishment of a pratyeka­buddha is not regarded as final or ultimate. They attain realization of the nature of dependent origination, the selflessness of the person, and a partial realization of the selflessness of phenomena, by observing the suchness of all that arises through interdependence. This is the result of progress in previous lives but, unlike a buddha, they do not have the necessary merit, compassion or motivation to teach others. They are named as “rhinoceros-like” (khaḍgaviṣāṇakalpa) for their preference for staying in solitude or as “congregators” (vargacārin) when their preference is to stay among peers.

One of the five or six classes of sentient beings, into which beings are born as the karmic fruition of past miserliness. As the term in Sanskrit means “the departed,” they are analogous to the ancestral spirits of Vedic tradition, the pitṛs, who starve without the offerings of descendants. It is also commonly translated as “hungry ghost” or “starving spirit,” as in the Chinese 餓鬼 e gui.They are sometimes said to reside in the realm of Yama, but are also frequently described as roaming charnel grounds and other inhospitable or frightening places along with piśācas and other such beings. They are particularly known to suffer from great hunger and thirst and the inability to acquire sustenance.

The ten strengths of a buddha: reflection, intention, application, insight, aspiration, vehicle, conduct, manifestation, awakening, and turning the Dharma wheel. The five strengths are faith, diligence, mindfulness, absorption, and knowledge. These are the same as the five powers .

Knowledge through the divine eye (lha’i mig gi shes pa), knowledge through remembering past lives (sngon gyi gnas rjes su dran pa’i rig pa), and the knowledge that defilements have ceased (zag pa zad pa’i rig pa).

Usually synonymous with the three realms of desire, form, and formlessness. Sometimes it means the realms of devas above, humans on the ground, and nāgas below ground.

Two of the basic forms of Buddhist meditation, which focus respectively on calming the mind and developing insight into the nature of phenomena.

The name of a gandharva.

See “very limit of reality.”

One of the Four Great Kings, he presides over the northern quarter and rules over the yakṣas. He is also known as Kubera.

This term has three meanings: (1) the ultimate nature, (2) the experience of the ultimate nature, and (3) the quiescent state of a worthy one (arhat) to be avoided by bodhisattvas.

One of the Four Great Kings, he presides over the southern quarter and rules over the kumbhāṇḍas.

The Gṛdhra­kūṭa, literally Vulture Peak, was a hill located in the kingdom of Magadha, in the vicinity of the ancient city of Rājagṛha (modern-day Rajgir, in the state of Bihar, India), where the Buddha bestowed many sūtras, especially the Great Vehicle teachings, such as the Prajñāpāramitā sūtras. It continues to be a sacred pilgrimage site for Buddhists to this day.

According to Buddhist tradition, one who is worthy of worship (pūjām arhati), or one who has conquered the enemies, the mental afflictions (kleśa-ari-hata-vat), and reached liberation from the cycle of rebirth and suffering. It is the fourth and highest of the four fruits attainable by śrāvakas. Also used as an epithet of the Buddha.

A class of nonhuman beings who inhabit forests, mountainous areas, and other natural spaces, or serve as guardians of villages and towns, and may be propitiated for health, wealth, protection, and other boons, or controlled through magic. According to tradition, their homeland is in the north, where they live under the rule of the Great King Vaiśravaṇa. Several members of this class have been deified as gods of wealth (these include the just-mentioned Vaiśravaṇa) or as bodhisattva generals of yakṣa armies, and have entered the Buddhist pantheon in a variety of forms, including, in tantric Buddhism, those of wrathful deities.
