The Sarvāstivāda (Sanskrit: 𑀲𑀭𑁆𑀯𑀸𑀲𑁆𑀢𑀺𑀯𑀸𑀤; Pali: 𑀲𑀩𑁆𑀩𑀢𑁆𑀣𑀺𑀯𑀸𑀤, romanized: Sabbatthivāda Chinese: 說一切有部; pinyin: Shuōyīqièyǒu Bù; Japanese: せついっさいうぶ; Korean: 설일체유부;Thai: สรวาสติวาท) was one of the early Buddhist schools established around the reign of Ashoka (third century BCE).[2] It was particularly known as an Abhidharma tradition, with a unique set of seven canonical Abhidharma texts.[3]
The Sarvāstivādins were one of the most influential Buddhist monastic groups, flourishing throughout North India, especially Kashmir and Central Asia, until the 7th century CE.[2] The orthodox Kashmiri branch of the school composed the large and encyclopedic Abhidharma Mahāvibhāṣa Śāstra around the time of the reign of Kanishka (c. 127–150 CE).[3] Because of this, orthodox Sarvāstivādins who upheld the doctrines in the Mahāvibhāṣa were called Vaibhāṣikas.[3]
According to the Theravādin Dīpavaṃsa, the Sarvāstivādins emerged from the older Mahīśāsaka school, but the Śāriputraparipṛcchā and the Samayabhedoparacanacakra state that the Mahīśāsaka emerged from the Sarvāstivāda.[4][5] The Sarvāstivādins are believed to have given rise to the Mūlasarvāstivāda and Sautrāntika schools, although the relationship between these groups has not yet been fully determined.
