“Original” or “primordial” buddha, the personification of innate enlightenment. See Buswell and Lopez 2014, p. 17.

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.

705–74. A famous and prolific translator, he is particularly renowned for his Chinese translations of Indian Buddhist esoteric works. He is known to have sailed from South India to China via Sri Lanka between 741 and 746. Not to be confused with the eleventh century paṇḍita of the same name who translated texts into Tibetan. Disciple of the translator and missionary Vajrabodhi.

One of the kings of the nāgas.

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.

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).

The Indic term buddha means “awakened one” and is used in Buddhism as an epithet for the historical Buddha Siddhārtha Gautama and other fully awakened beings in general. Buddha is a past participle from the Sanskrit root budh, meaning “to awaken,” “to understand,” or “to become aware.”

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.

A list of factors conducive to and forming the components of awakening, including the following: mindfulness (smṛti), analytic observation of things (dharma­pravicaya), heroic effort (vīrya), joy (prīti), tranquility (praśrabdhi), concentration (samādhi), and equanimity (upekṣā).

The four truths that the Buddha transmitted in his first teaching: (1) suffering, (2) the origin of suffering, (3) the cessation of suffering, and (4) the path to the cessation of suffering.

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.

Refers to the five acts of immediate retribution (pañcānantarya), for which one will be reborn in hell immediately after death, without any intervening stages: killing an arhat, killing one’s father, killing one’s mother, causing a schism in the monastic community, and maliciously drawing blood from a tathāgata.

The name applied to the supreme worldly god, whatever his identity. Literally “lord,” this term is often an epithet for the god Śiva.

Common epithet of Mañjuśrī, meaning “one with a gentle voice.”

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.

Tripidium bengalense, a plant species indigenous to Iran, Afghanistan, Pakistan, northern India, Nepal, Bangladesh, and Myanmar. Its fiber was commonly sourced for the manufacture of ropes.

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.

In Sanskrit, the term nirvāṇa literally means “extinguishment” and the Tibetan mya ngan las ’das pa literally means “gone beyond sorrow.” As a general term, it refers to the cessation of all suffering, afflicted mental states (kleśa), and causal processes (karman) that lead to rebirth and suffering in cyclic existence, as well as to the state in which all such rebirth and suffering has permanently ceased.

More specifically, three main types of nirvāṇa are identified. (1) The first type of nirvāṇa, called nirvāṇa with remainder (sopadhiśeṣanirvāṇa), is the state in which arhats or buddhas have attained awakening but are still dependent on the conditioned aggregates until their lifespan is exhausted. (2) At the end of life, given that there are no more causes for rebirth, these aggregates cease and no new aggregates arise. What occurs then is called nirvāṇa without remainder ( anupadhiśeṣanirvāṇa), which refers to the unconditioned element (dhātu) of nirvāṇa in which there is no remainder of the aggregates. (3) The Mahāyāna teachings distinguish the final nirvāṇa of buddhas from that of arhats, the nirvāṇa of arhats not being considered ultimate. The buddhas attain what is called nonabiding nirvāṇa (apratiṣṭhitanirvāṇa), which transcends the extremes of saṃsāra and nirvāṇa, i.e., existence and peace. This is the nirvāṇa that is the goal of the Mahāyāna path.

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.

Major deity in the pantheon of the classical Indian religious traditions.

Son of Śiva and commander of his hosts.

A collective name for the realms of animals, anguished spirits (pretas), and hell beings.

The ten stations of spiritual realization to be attained by those on the bodhisattva path, prior to their attainment of buddhahood. These are also presented as seven, thirteen, or fifty-two.

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

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

The name of one of the oldest of the Vedic gods, associated with the waters.

King of the asuras.

A sacred utterance or spell made for the purpose of attaining either worldly or transcendent benefits. Although a technical term in its own right, vidyāmantra is often used interchangeably with terms such as dhāraṇī, dhāraṇīmantra, and guhyamantra.

One of the principal deities in the Brahmanical pantheon.

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.
