Vaibhashika

The Vaibhāṣika was an early Buddhist subschool formed by adherents of the Mahāvibhāṣa Śāstra, comprising the orthodox Kasmiri branch of the Sarvāstivāda school. The Vaibhāśika-Sarvāstivāda, which had by far the most "comprehensive edifice of doctrinal systematics" of the early Buddhist schools, was widely influential in India and beyond.
