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.

The seven branches of awakening are: mindfulness, analysis of the dharmas, diligence, joy, pliability, absorption, equanimity.

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 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.

Also refers to an atheist, a false doctrine, the impious, a hypocrite, and an imposter.

One of the first Buddhist monasteries, located in a park outside Śrāvastī, the capital of the ancient kingdom of Kośala in northern India. This park was originally owned by Prince Jeta, hence the name Jetavana, meaning Jeta’s grove. The wealthy merchant Anāthapiṇḍada, wishing to offer it to the Buddha, sought to buy it from him, but the prince, not wishing to sell, said he would only do so if Anāthapiṇḍada covered the entire property with gold coins. Anāthapiṇḍada agreed, and managed to cover all of the park except the entrance, hence the name Anāthapiṇḍadasyārāmaḥ, meaning Anāthapiṇḍada’s park. The place is usually referred to in the sūtras as “Jetavana, Anāthapiṇḍada’s park,” and according to the Saṃghabhedavastu the Buddha used Prince Jeta’s name in first place because that was Prince Jeta’s own unspoken wish while Anāthapiṇḍada was offering the park. Inspired by the occasion and the Buddha’s use of his name, Prince Jeta then offered the rest of the property and had an entrance gate built. The Buddha specifically instructed those who recite the sūtras to use Prince Jeta’s name in first place to commemorate the mutual effort of both benefactors.

Anāthapiṇḍada built residences for the monks, to house them during the monsoon season, thus creating the first Buddhist monastery. It was one of the Buddha’s main residences, where he spent around nineteen rainy season retreats, and it was therefore the setting for many of the Buddha’s discourses and events. According to the travel accounts of Chinese monks, it was still in use as a Buddhist monastery in the early fifth century ᴄᴇ, but by the sixth century it had been reduced to ruins.

One of the five trees of Indra’s paradise, its heavenly flowers often rain down in salutation of the buddhas and bodhisattvas and are said to be very bright and aromatic, gladdening the hearts of those who see them. In our world, it is a tree native to India, Erythrina indica or Erythrina variegata, commonly known as the Indian coral tree, mandarava tree, flame tree, and tiger’s claw. In the early spring, before its leaves grow, the tree is fully covered in large flowers, which are rich in nectar and attract many birds. Although the most widespread coral tree has red crimson flowers, the color of the blossoms is not usually mentioned in the sūtras themselves, and it may refer to some other kinds, like the rarer Erythrina indica alba, which boasts white flowers.

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.

The Buddha is said to have spent about twenty-five rainy seasons with his disciples in Śrāvastī, thus it is named as the setting of numerous events and teachings. It is located in present-day Uttar Pradesh in northern India.

An Indian paṇḍita who was resident in Tibet during the late eighth and early ninth centuries.

A buddha who resides in the eastern buddha realm called Tiers of Purification.

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.

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.

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.
