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.

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).

One of the “eight close sons of the Buddha,” he is also known as the bodhisattva who embodies compassion. In certain tantras, he is also the lord of the three families, where he embodies the compassion of the buddhas. In Tibet, he attained great significance as a special protector of Tibet, and in China, in female form, as Guanyin, the most important bodhisattva in all of East Asia.

Yeshé Dé (late eighth to early ninth century) was the most prolific translator of sūtras into Tibetan. Altogether he is credited with the translation of more than one hundred sixty sūtra translations and more than one hundred additional translations, mostly on tantric topics. In spite of Yeshé Dé’s great importance for the propagation of Buddhism in Tibet during the imperial era, only a few biographical details about this figure are known. Later sources describe him as a student of the Indian teacher Padmasambhava, and he is also credited with teaching both sūtra and tantra widely to students of his own. He was also known as Nanam Yeshé Dé, from the Nanam (sna nam) clan.

The Medicine Buddha, the thus-gone one residing in the buddhafield Vaiḍūryanirbhāsa. Also called Bhaiṣajya­guru­vaiḍūrya­prabha­rāja.

One of the Seven Thus-Gone Ones, often referred to as the Medicine Buddha. Also called Bhaiṣajya­guru­vaiḍūrya­prabha.

The name of a nāga who is invoked in the Dhāraṇī of Vaiḍūryaprabha (Toh 505).

In Buddhist literature, this is an epithet applied to buddhas, most often to Śākyamuni. The Sanskrit term generally means “possessing fortune,” but in specifically Buddhist contexts it implies that a buddha is in possession of six auspicious qualities (bhaga) associated with complete awakening. The Tibetan term‍—where bcom is said to refer to “subduing” the four māras, ldan to “possessing” the great qualities of buddhahood, and ’das to “going beyond” saṃsāra and nirvāṇa‍—possibly reflects the commentarial tradition where the Sanskrit bhagavat is interpreted, in addition, as “one who destroys the four māras.” This is achieved either by reading bhagavat as bhagnavat (“one who broke”), or by tracing the word bhaga to the root √bhañj (“to break”).

A being who is dedicated to the cultivation and fulfilment of the altruistic intention to attain perfect buddhahood, traversing the ten bodhisattva levels (daśabhūmi, sa bcu). Bodhisattvas purposely opt to remain within cyclic existence in order to liberate all sentient beings, instead of simply seeking personal freedom from suffering. In terms of the view, they realize both the selflessness of persons and the selflessness of phenomena.

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).

A member of the highest of the four castes in Indian society, which is closely associated with religious vocations.

The name of a bodhisattva.

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 name of a bodhisattva.

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.

One of the Seven Thus-Gone Ones.

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.

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.

The name of a bodhisattva.

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.”

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).

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.

The name of a bodhisattva.

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 name of a bodhisattva.

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.

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.”

The name of a bodhisattva.

One of the Seven Thus-Gone Ones.

A monastery in Western Tibet that was one of a number of important institutions during the early decades of the later dissemination of the Dharma in Tibet.

A frequently used synonym for buddha. According to different explanations, it can be read as tathā-gata, literally meaning “one who has thus gone,” or as tathā-āgata, “one who has thus come.” Gata, though literally meaning “gone,” is a past passive participle used to describe a state or condition of existence. Tatha­(tā), often rendered as “suchness” or “thusness,” is the quality or condition of things as they really are, which cannot be conveyed in conceptual, dualistic terms. Therefore, this epithet is interpreted in different ways, but in general it implies one who has departed in the wake of the buddhas of the past, or one who has manifested the supreme awakening dependent on the reality that does not abide in the two extremes of existence and quiescence. It is also often used as a specific epithet of the Buddha Śākyamuni.

Prolific eleventh-century Tibetan translator also known as Naktso Lotsawa (nag tsho lo tsA ba). He was sent to India by Lhalama Yeshe-Ö (lha bla ma ye shes ’od), the king of Western Tibet, and his grand-nephew Changchub-Ö (byang chub ’od) to invite Atiśa to Tibet.
