A royal city in a past world system.

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 member of the class of celestial female beings known for their great beauty.

A bodhisattva.

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).

A past buddha.

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).

An ideal monarch or emperor who, as the result of the merit accumulated in previous lifetimes, rules over a vast realm in accordance with the Dharma. Such a monarch is called a cakravartin because he bears a wheel (cakra) that rolls (vartate) across the earth, bringing all lands and kingdoms under his power. The cakravartin conquers his territory without causing harm, and his activity causes beings to enter the path of wholesome actions. According to Vasubandhu’s Abhidharmakośa, just as with the buddhas, only one cakravartin appears in a world system at any given time. They are likewise endowed with the thirty-two major marks of a great being (mahāpuruṣalakṣaṇa), but a cakravartin’s marks are outshined by those of a buddha. They possess seven precious objects: the wheel, the elephant, the horse, the wish-fulfilling gem, the queen, the general, and the minister. An illustrative passage about the cakravartin and his possessions can be found in The Play in Full (Toh 95), 3.3–3.13. Vasubandhu lists four types of cakravartins: (1) the cakravartin with a golden wheel (suvarṇacakravartin) rules over four continents and is invited by lesser kings to be their ruler; (2) the cakravartin with a silver wheel (rūpyacakravartin) rules over three continents and his opponents submit to him as he approaches; (3) the cakravartin with a copper wheel (tāmracakravartin) rules over two continents and his opponents submit themselves after preparing for battle; and (4) the cakravartin with an iron wheel (ayaścakravartin) rules over one continent and his opponents submit themselves after brandishing weapons.

In the most general sense the devas‍—the term is cognate with the English divine‍—are a class of celestial beings who frequently appear in Buddhist texts, often at the head of the assemblies of nonhuman beings who attend and celebrate the teachings of the Buddha Śākyamuni and other buddhas and bodhisattvas. In Buddhist cosmology the devas occupy the highest of the five or six “destinies” (gati) of saṃsāra among which beings take rebirth. The devas reside in the devalokas, “heavens” that traditionally number between twenty-six and twenty-eight and are divided between the desire realm (kāmadhātu), form realm (rūpadhātu), and formless realm (ārūpyadhātu). A being attains rebirth among the devas either through meritorious deeds (in the desire realm) or the attainment of subtle meditative states (in the form and formless realms). While rebirth among the devas is considered favorable, it is ultimately a transitory state from which beings will fall when the conditions that lead to rebirth there are exhausted. Thus, rebirth in the god realms is regarded as a diversion from the spiritual path.

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.

The “sphere of dharmas,” a synonym for the nature of things.

Four gods who live on the lower slopes (fourth level) of Mount Meru in the eponymous Heaven of the Four Great Kings (Cāturmahā­rājika, rgyal chen bzhi’i ris) and guard the four cardinal directions. Each is the leader of a nonhuman class of beings living in his realm. They are Dhṛtarāṣṭra, ruling the gandharvas in the east; Virūḍhaka, ruling over the kumbhāṇḍas in the south; Virūpākṣa, ruling the nāgas in the west; and Vaiśravaṇa (also known as Kubera) ruling the yakṣas in the north. Also referred to as Guardians of the World or World Protectors (lokapāla, ’jig rten skyong ba).

The first teaching of the Buddha, covering suffering, the origin of suffering, the cessation of suffering, and the path to the cessation of suffering. They are named “truths of the noble ones” since the “noble ones” (ārya) are the ones who have perceived them perfectly and without error. Also rendered here simply as “four noble truths.”

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.”

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.

In the most general sense the devas‍—the term is cognate with the English divine‍—are a class of celestial beings who frequently appear in Buddhist texts, often at the head of the assemblies of nonhuman beings who attend and celebrate the teachings of the Buddha Śākyamuni and other buddhas and bodhisattvas.

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.

A bodhisattva.

The lord of the Trāyastriṃśa heaven on the summit of Mount Sumeru. As one of the eight guardians of the directions, Indra guards the eastern quarter. In Buddhist sūtras, he is a disciple of the Buddha and protector of the Dharma and its practitioners. He is often referred to by the epithets Śatakratu, Śakra, and Kauśika.

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.

A cosmic period of time, sometimes equivalent to the time when a world system appears, exists, and disappears. According to the traditional Abhidharma understanding of cyclical time, a great eon (mahākalpa) is divided into eighty lesser eons. In the course of one great eon, the universe takes form and later disappears. During the first twenty of the lesser eons, the universe is in the process of creation and expansion; during the next twenty it remains; during the third twenty, it is in the process of destruction; and during the last quarter of the cycle, it remains in a state of empty stasis. A fortunate, or good, eon (bhadrakalpa) refers to any eon in which more than one buddha appears.

A class of nonhuman beings that resemble humans to the degree that their very name‍—which means “is that human?”‍—suggests some confusion as to their divine status. Kinnaras are mythological beings found in both Buddhist and Brahmanical literature, where they are portrayed as creatures half human, half animal. They are often depicted as highly skilled celestial musicians.

A vast legendary lake on the other side of the Himalayas. Only those with miraculous powers can go there. It is said to be the source of the world’s four great rivers. (Provisional 84000 definition. New definition forthcoming.)

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).

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.

First of the five aggregates. Physical forms include the subtle and coarse forms derived from the primary material elements.

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.

The objects of consciousness, namely, objects of sight up through mental objects.

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.

A bodhisattva.

A world system in the past.

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.

The name for our world system, the universe of a thousand million worlds, or trichiliocosm, in which the four-continent world is located. Each trichiliocosm is ruled by a god Brahmā; thus, in this context, he bears the title of Sahāṃpati, Lord of Sahā. The world system of Sahā, or Sahālokadhātu, is also described as the buddhafield of the Buddha Śākyamuni where he teaches the Dharma to beings. The name Sahā possibly derives from the Sanskrit √sah, “to bear, endure, or withstand.” It is often interpreted as alluding to the inhabitants of this world being able to endure the suffering they encounter. The Tibetan translation, mi mjed, follows along the same lines. It literally means “not painful,” in the sense that beings here are able to bear the suffering they experience.

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.

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 Sanskrit literally means “attainment,” and is used to refer specifically to meditative attainment and to particular meditative states. The Tibetan translators interpreted it as sama-āpatti, which suggests the idea of “equal” or “level”; however, they also parsed it as sam-āpatti, in which case it would have the sense of “concentration” or “absorption,” much like samādhi, but with the added sense of “attainment.”

A general term applied to spiritual practitioners who live as ascetic mendicants. In Buddhist texts, the term usually refers to Buddhist monastics, but it can also designate a practitioner from other ascetic/monastic spiritual traditions. In this context śramaṇa is often contrasted with the term brāhmaṇa (bram ze), which refers broadly to followers of the Vedic tradition. Any renunciate, not just a Buddhist, could be referred to as a śramaṇa if they were not within the Vedic fold. The epithet Great Śramaṇa is often applied to the Buddha.

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.”

According to ancient Buddhist cosmology, this is the great mountain forming the axis of the universe. At its summit is Sudarśana, home of Śakra and his thirty-two gods, and on its flanks live the asuras. The mount has four sides facing the cardinal directions, each of which is made of a different precious stone. Surrounding it are several mountain ranges and the great ocean where the four principal island continents lie: in the south, Jambudvīpa (our world); in the west, Godānīya; in the north, Uttarakuru; and in the east, Pūrvavideha. Above it are the abodes of the desire realm gods. It is variously referred to as Meru, Mount Meru, Sumeru, and Mount Sumeru.

Emptiness, being without attributes, and being without aspiration. Also known as the “three doors of liberation.”

The three realms that contain all the various kinds of existence in saṃsāra: the desire realm, the form realm, and the formless 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).

A bodhisattva.

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.

A term which is generally used to refer to a wide range of spiritual practices. It literally means to be merged with or “yoked to,” in the sense of being fully immersed in one’s respective discipline. The Tibetan specifies “union with the natural state.”
