MulasarvastivadaThe Mūlasarvāstivāda (Sanskrit: मूलसर्वास्तिवाद; ) was one of the early Buddhist schools of India. The origins of the Mūlasarvāstivāda school and their relationship to the Sarvāstivāda school still remain largely unknown, although various theories exist. The continuity of the Mūlasarvāstivāda monastic order remains in Tibetan Buddhism, although until recently, only Mūlasarvāstivādin bhikṣus (monks) existed. The Tibetan Buddhist tradition of bhikṣuṇī (nuns) officially commenced in Bhutan on 23 June 2022, when 144 women were ordained.
VinayaThe Vinaya texts (Pali & Sanskrit: विनय) are texts of the Buddhist canon (Tripitaka) that also contain the rules and precepts for fully ordained monks and nuns of Buddhist Sanghas (community of like-minded sramanas). The precepts were initially developed thirteen years after the Buddha's enlightenment. Three parallel Vinaya school traditions remain in use by modern ordained sanghas: the Theravada (Sri Lanka & Southeast Asia), Mulasarvastivada (Tibetan Buddhism and the Himalayan region) and Dharmaguptaka (Taiwan and East Asian Buddhism).
MahīśāsakaMahīśāsaka (महीशासक; ) is one of the early Buddhist schools according to some records. Its origins may go back to the dispute in the Second Buddhist council. The Dharmaguptaka sect is thought to have branched out from Mahīśāsaka sect toward the end of the 2nd or the beginning of the 1st century BCE. There are two general accounts of the circumstances surrounding the origins of the Mahīśāsakas. The Theravādin Dipavamsa asserts that the Mahīśāsaka sect gave rise to the Sarvāstivāda sect.
KanishkaKanishka I (Sanskrit: कनिष्क, ; Greco-Bactrian: Κανηϸκε Kanēške; Kharosthi: 𐨐𐨞𐨁𐨮𐨿𐨐 ; Brahmi: ), Kanishka or Kanishka the Great, was an emperor of the Kushan dynasty, under whose reign (127–150 CE) the empire reached its zenith. He is famous for his military, political, and spiritual achievements. A descendant of Kujula Kadphises, founder of the Kushan empire, Kanishka came to rule an empire extending from Central Asia and Gandhara to Pataliputra on the Gangetic plain.
DharmaguptakaThe Dharmaguptaka (Sanskrit: धर्मगुप्तक; ) are one of the eighteen or twenty early Buddhist schools, depending on the source. They are said to have originated from another sect, the Mahīśāsakas. The Dharmaguptakas had a prominent role in early Central Asian and Chinese Buddhism, and their Prātimokṣa (monastic rules for bhikṣus and bhikṣuṇīs) are still in effect in East Asian countries to this day, including China, Vietnam, Korea, and Japan as well as the Philippines.
SarvastivadaThe Sarvāstivāda (𑀲𑀩𑁆𑀩𑀢𑁆𑀣𑀺𑀯𑀸𑀤, श्र्वास्तिवाद; ) was one of the early Buddhist schools established around the reign of Ashoka (third century BCE). It was particularly known as an Abhidharma tradition, with a unique set of seven Abhidharma works. The Sarvāstivādins were one of the most influential Buddhist monastic groups, flourishing throughout North India (especially Kashmir) and Central Asia until the seventh century.
MahākāśyapaMahākāśyapa (Mahākassapa) was one of the principal disciples of Gautama Buddha. He is regarded in Buddhism as an enlightened disciple, being foremost in ascetic practice. Mahākāśyapa assumed leadership of the monastic community following the paranirvāṇa (death) of the Buddha, presiding over the First Buddhist Council. He was considered to be the first patriarch in a number of Early Buddhist schools and continued to have an important role as patriarch in the Chan and Zen traditions.
