The fire god.

The buddha of the western buddhafield of Sukhāvatī, where fortunate beings are reborn to make further progress toward spiritual maturity. Amitābha made his great vows to create such a realm when he was a bodhisattva called Dharmākara. In the Pure Land Buddhist tradition, popular in East Asia, aspiring to be reborn in his buddha realm is the main emphasis; in other Mahāyāna traditions, too, it is a widespread practice. For a detailed description of the realm, see The Display of the Pure Land of Sukhāvatī, Toh 115. In some tantras that make reference to the five families he is the tathāgata associated with the lotus family.

Amitābha, “Infinite Light,” is also known in many Indian Buddhist works as Amitāyus, “Infinite Life.” In both East Asian and Tibetan Buddhist traditions he is often conflated with another buddha named “Infinite Life,” Aparimitāyus, or “Infinite Life and Wisdom,”Aparimitāyurjñāna, the shorter version of whose name has also been back-translated from Tibetan into Sanskrit as Amitāyus but who presides over a realm in the zenith. For details on the relation between these buddhas and their names, see The Aparimitāyurjñāna Sūtra (1) Toh 674, i.9.

The buddha residing in the western buddha realm of Sukhāvatī, he is sometimes identified with Amitābha. More commonly translated into Tibetan as tshe dpag med.

A class of nonhuman beings believed to cause epilepsy, fits, and loss of memory. As their name suggests‍—the Skt. apasmāra literally means “without memory” and the Tib. brjed byed means “causing forgetfulness”‍—they are defined by the condition they cause in affected humans, and the term can refer to any nonhuman being that causes such conditions, whether a bhūta, a piśāca, or other.

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.

This term in its broadest sense can refer to any being, whether human, animal, or nonhuman. However, it is often used to refer to a specific class of nonhuman beings, especially when bhūtas are mentioned alongside rākṣasas, piśācas, or pretas. In common with these other kinds of nonhumans, bhūtas are usually depicted with unattractive and misshapen bodies. Like several other classes of nonhuman beings, bhūtas take spontaneous birth. As their leader is traditionally regarded to be Rudra-Śiva (also known by the name Bhūta), with whom they haunt dangerous and wild places, bhūtas are especially prominent in Śaivism, where large sections of certain tantras concentrate on them.

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”).

The highest caste in traditional Indian society.

The Tibetan translates both stūpa and caitya with the same word, mchod rten, meaning “basis” or “recipient” of “offerings” or “veneration.” Pali: cetiya.

A caitya, although often synonymous with stūpa, can also refer to any site, sanctuary or shrine that is made for veneration, and may or may not contain relics.

A stūpa, literally “heap” or “mound,” is a mounded or circular structure usually containing relics of the Buddha or the masters of the past. It is considered to be a sacred object representing the awakened mind of a buddha, but the symbolism of the stūpa is complex, and its design varies throughout the Buddhist world. Stūpas continue to be erected today as objects of veneration and merit making.

A wheel.

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 secret palace in Sukhāvatī.

The Lord of Death in both Buddhist and Hindu traditions, Yama is said to uphold the Dharma by reviewing the karma of the dead and thereby determining their next rebirth.

Indian preceptor and translator.

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).

See “Four Great Kings.”

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.

This can refer either to the sal (or sala) tree (Shorea robusta) or to a great (mahā) household (śāla). The Buddha was said to have been born and died beneath a sāla tree.

The casting of a prescribed offering into a ritual fire. The practice of homa is first attested in pre-Buddhist Vedic literature and serves as a core, pervasive ritual paradigm in exoteric and esoteric rites in both Buddhist and non-Buddhist traditions into modern times. In Buddhist esoteric rites, the ritual offerings are made repeatedly, with each throw accompanied by a single repetition of the respective mantra.

Not one of the normal four “castes” of Indian society, but presumably here a term referring to nonmonastics.

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 ritual manual.

A subgroup of pūtanas, a class of disease-causing spirits associated with cemeteries and dead bodies. The name probably derives from the Skt. pūta, “foul-smelling,” as reflected also in the Tib. srul po. The smell of a pūtana is variously described in the texts as resembling that of a billy goat or a crow, and the smell of a kaṭapūtana, as its name suggests, could resemble a corpse, kaṭa being one of the names for “corpse.” The morbid condition caused by pūtanas comes in various forms, with symptoms such as fever, vomiting, diarrhea, skin eruptions, and festering wounds, the latter possibly explaining the association with bad smells.

1040–11; the Tibetan translator and second throne-holding Sakya heirarch, also known as Bari Lotsāwa or Rinchen Drak (rin chen grags) who, along with this and many other texts, also translated ninety-three sādhanas that are grouped together under his name in the Tengyur.

The ruling caste in the traditional four-caste hierarchy of India, associated with warriors, the aristocracy, and kings.

Layman who holds householder’s vows.

Laywoman who holds householder’s vows.

Epithet of Śakra.

Also translated as “lower rebirths.”

The term bhikṣu, often translated as “monk,” refers to the highest among the eight types of prātimokṣa vows that make one part of the Buddhist assembly. The Sanskrit term literally means “beggar” or “mendicant,” referring to the fact that Buddhist monks and nuns‍—like other ascetics of the time‍—subsisted on alms (bhikṣā) begged from the laity.

In the Tibetan tradition, which follows the Mūlasarvāstivāda Vinaya, a monk follows 253 rules as part of his moral discipline. A nun (bhikṣuṇī; dge slong ma) follows 364 rules. A novice monk (śrāmaṇera; dge tshul) or nun (śrāmaṇerikā; dge tshul ma) follows thirty-six rules of moral discipline (although in other vinaya traditions novices typically follow only ten).

A seal, in both the literal and metaphoric sense. Mudrā is also the name given to an array of symbolic hand gestures, which range from the gesture of touching the earth displayed by the Buddha upon attaining awakening to the numerous gestures used in tantric rituals to symbolize offerings, consecrations, etc. Iconographically, mudrās are used as a way of communicating an action performed by the deity or a specific aspect a deity or buddha is displaying, in which case the same figure can be depicted using different hand gestures to signify that they are either meditating, teaching, granting freedom from fear, etc. In Tantric texts, the term is also used to designate the female spiritual consort in her various aspects.

The term bhikṣuṇī, often translated as “nun,” refers to the highest among the eight types of prātimokṣa vows that make one part of the Buddhist assembly. The Sanskrit term bhikṣu (to which the female grammatical ending ṇī is added) literally means “beggar” or “mendicant,” referring to the fact that Buddhist nuns and monks‍—like other ascetics of the time‍—subsisted on alms (bhikṣā) begged from the laity. In the Tibetan tradition, which follows the Mūlasarvāstivāda Vinaya, a bhikṣuṇī follows 364 rules and a bhikṣu follows 253 rules as part of their moral discipline.

For the first few years of the Buddha’s teachings in India, there was no ordination for women. It started at the persistent request and display of determination of Mahāprajāpatī, the Buddha’s stepmother and aunt, together with five hundred former wives of men of Kapilavastu, who had themselves become monks. Mahāprajāpatī is thus considered to be the founder of the nun’s order.

An epithet of Avalokiteśvara.

A class of nonhuman beings that, like several other classes of nonhuman beings, take spontaneous birth. Ranking below rākṣasas, they are less powerful and more akin to pretas. They are said to dwell in impure and perilous places, where they feed on impure things, including flesh. This could account for the name piśāca, which possibly derives from √piś, to carve or chop meat, as reflected also in the Tibetan sha za, “meat eater.” They are often described as having an unpleasant appearance, and at times they appear with animal bodies. Some possess the ability to enter the dead bodies of humans, thereby becoming so-called vetāla, to touch whom is fatal.

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. Detailed descriptions of their realm and experience, including a list of the thirty-six classes of pretas, can be found in The Application of Mindfulness of the Sacred Dharma, Toh 287, 2.­1281– 2.1482.

The five Pure Abodes are the highest heavens of the Form Realm (rūpadhātu). They are called “pure abodes” because ordinary beings (pṛthagjana; so so’i skye bo) cannot be born there; only those who have achieved the fruit of a non-returner (anāgāmin; phyir mi ’ong) can be born there. A summary presentation of them is found in the third chapter of Vasubandhu's Abhidharmakośa, although they are repeatedly mentioned as a set in numerous sūtras, tantras, and vinaya texts.

The five Pure Abodes are the last five of the seventeen levels of the Form Realm. Specifically, they are the last five of the eight levels of the upper Form Realm‍—which corresponds to the fourth meditative concentration (dhyāna; bsam gtan)‍—all of which are described as “immovable” (akopya; mi g.yo ba) since they are never destroyed during the cycles of the destruction and reformation of a world system. In particular, the five are Abṛha (mi che ba), the inferior heaven; Atapa (mi gdung ba), the heaven of no torment; Sudṛśa (gya nom snang), the heaven of sublime appearances; Sudarśana (shin tu mthong), the heaven of the most beautiful to behold; and Akaniṣṭha (’og min), the highest heaven.

Yaśomitra explains their names, stating: (1) because those who abide there can only remain for a fixed amount of time, before they are plucked out (√bṛh, bṛṃhanti) of that heaven, or because it is not as extensive (abṛṃhita) as the others in the pure realms, that heaven is called the inferior heaven (abṛha; mi che ba); (2) since the afflictions can no longer torment (√tap, tapanti) those who reside there because of their having attained a particular samādhi, or because their state of mind is virtuous, they no longer torment (√tap, tāpayanti) others, this heaven, consequently, is called the heaven of no torment (atapa; mi gdung ba); (3) since those who reside there have exceptional (suṣṭhu) vision because what they see (√dṛś, darśana) is utterly pure, that heaven is called the heaven of sublime appearances (sudṛśa; gya nom snang); (4) because those who reside there are beautiful gods, that heaven is called the heaven of the most beautiful to behold (sudarśana; shin tu mthong); and (5) since it is not lower (na kaniṣṭhā) than any other heaven because there is no other place superior to it, this heaven is called the highest heaven (akaniṣṭha; ’og min) since it is the uppermost.

A class of disease-causing spirits associated with cemeteries and dead bodies. The name probably derives from the Skt. pūta, “foul-smelling,” as reflected also in the Tib. srul po. The smell is variously described in the texts as resembling that of a billy goat or a crow. The morbid condition caused by the spirit shares its name and comes in various forms, with symptoms such as fever, vomiting, diarrhea, skin eruptions, and festering wounds, the latter possibly explaining the association with bad smells.

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 land of the dead ruled over by the Lord of Death. In Buddhism it refers to the preta realm, where beings generally suffer from hunger and thirst, which in traditional Brahmanism is the fate of those departed without descendants to make ancestral offerings.

Derived from the Sanskrit verb √sādh, “to accomplish,” the term sādhana most generically refers to any method that brings about the accomplishment of a desired goal. In Buddhist literature, the term is often specifically applied to tantric practices that involve ritual engagement with deities, mantra recitation, the visualized creation and dissolution of deity maṇḍalas, etc. Sādhanas are aimed at both actualizing spiritual attainments (siddhi) and reaching liberation. The Tibetan translation sgrub thabs means “method of accomplishment.”

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.

Amitābha’s pure realm.
