King of Magadha who was initially hostile to the Buddha before later becoming his devoted follower.

The Indian gooseberry (Phyllanthus emblica).

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 fourth and final attainment of śrāvakas, this term refers to a person who has relinquished all their afflictive emotions and will enter nirvāṇa without remainder upon their death.

The king of Magadha and a great patron of the Buddha. His birth coincided with the Buddha’s, and his father, King Mahāpadma, named him “Essence of Gold” after mistakenly attributing the brilliant light that marked the Buddha’s birth to the birth of his son by Queen Bimbī (“Goldie”). Accounts of Bimbisāra’s youth and life can be found in The Chapter on Going Forth (Toh 1-1, Pravrajyāvastu).King Śreṇya Bimbisāra first met with the Buddha early on, when the latter was the wandering mendicant known as Gautama. Impressed by his conduct, Bimbisāra offered to take Gautama into his court, but Gautama refused, and Bimbisāra wished him success in his quest for awakening and asked him to visit his palace after he had achieved his goal. One account of this episode can be found in the sixteenth chapter of The Play in Full (Toh 95, Lalitavistara). There are other accounts where the two meet earlier on in childhood; several episodes can be found, for example, in The Hundred Deeds (Toh 340, Karmaśataka). Later, after the Buddha’s awakening, Bimbisāra became one of his most famous patrons and donated to the saṅgha the Bamboo Grove, Veṇuvana, at the outskirts of the capital of Magadha, Rājagṛha, where he built residences for the monks. Bimbisāra was imprisoned and killed by his own son, the prince Ajātaśatru, who, influenced by Devadatta, sought to usurp his father’s throne.

A Tibetan translator active in Tibet in the late eighth to early ninth century.

The western continent in Buddhist cosmology.

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.

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.

The northern continent in Buddhist cosmology.

A measure of distance. The exact distance can vary according to different sources; however, it is generally said to be between six and fourteen kilometers.

A kingdom on the banks of the Ganges (in the southern part of the modern-day Indian state of Bihar), whose capital was at Pāṭaliputra (modern-day Patna). During the life of the Buddha Śākyamuni, it was the dominant kingdom in north-central India and is home to many of the most important Buddhist sites, including Bodh Gayā, Nālandā, and its capital Rājagṛha.

The third of the four attainments of śrāvakas, this term refers to a person who will no longer take rebirth in the Desire Realm (kāmadhātu), but either be reborn in the Pure Abodes (śuddhāvāsa) or reach the state of an arhat in their current lifetime.

The second of the four attainments of śrāvakas, this term is used for those who will take only one more rebirth before attaining nirvāṇa.

Indra’s palace on the summit of Sumeru.

Nirvāṇa, the state beyond sorrow, denotes the ultimate attainment of liberation, the permanent cessation of all suffering and the afflicted mental states that cause and perpetuate suffering, along with all misapprehension with regard to the nature of reality. As such, it is the antithesis of cyclic existence. Three types of nirvāṇa are identified: (1) the residual nirvāṇa where the person is still dependent on conditioned psycho-physical aggregates, (2) the non-residual nirvāṇa after an arhat or buddha has passed away, when the conditioned psycho-physical aggregates have ceased, and (3) the non-abiding nirvāṇa transcending the extremes of phenomenal existence and quiescence. Parinirvāṇa generally refers to the non-residual attainment.

Those who attain buddhahood through their own contemplation as a result of progress in previous lives, but who are born in a time when a buddha’s doctrine is no longer available in the world and so remain either in solitude or among peers, without teaching the path to liberation to others.

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.

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.”

During the life of the Buddha, Śrāvastī was the capital city of the powerful kingdom of Kośala, ruled by King Prasenajit, who became a follower and patron of the Buddha. It was also the hometown of Anāthapiṇḍada, the wealthy patron who first invited the Buddha there, and then offered him a park known as Jetavana, Prince Jeta’s Grove, which became one of the first Buddhist monasteries. 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.

The first of the four attainments of śrāvakas, this term refers to a person who has entered the “stream” of practice that leads to nirvāṇa.

The largest universe described in Buddhist cosmology. This term, in Abhidharma cosmology, refers to 1,000³ world systems, i.e., 1,000 “dichiliocosms” or “two thousand great thousand world realms” (dvi­sāhasra­mahā­sāhasra­lokadhātu), which are in turn made up of 1,000 first-order world systems, each with its own Mount Sumeru, continents, sun and moon, etc.
