Sarvastivada

The Sarvāstivāda (Sanskrit: 𑀲𑀭𑁆𑀯𑀸𑀲𑁆𑀢𑀺𑀯𑀸𑀤) 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 canonical Abhidharma texts.

Sarvāstivāda is a Sanskrit term that can be glossed as: "the theory of all that exists". The Sarvāstivāda argued that all dharmas (phenomena) exist in the past, present and future, the "three times". Vasubandhu's Abhidharmakośa-bhāsya states that "He who affirms the existence of the dharmas of the three time periods [past, present and future] is held to be a Sarvāstivādin."

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. 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). Because of this, orthodox Sarvāstivādins who upheld the doctrines in the Mahāvibhāṣa were called Vaibhāṣikas.
