Saṃghabhadra

Sanghabhadra was an Indian scholar monk of the Sarvāstivāda Vaibhāṣika and "undoubtedly one of the most brilliant Abhidharma masters in India". Born in Kashmir, he was a contemporary of the Buddhist philosopher Vasubandhu. According to K.L. Dhammajoti, his work forms the most mature and refined form of Vaibhāṣika philosophy. His two main works, the *Nyāyānusāra and the *Abhidharmasamayapradīpikā, are very important sources for late Vaibhāṣika thought. He is referenced by various important Buddhist figures, such as Xuanzang, Kuiji, Sthiramati, and Śāntarakṣita who see him as the most authoritative of the Vaibhāṣika Abhidharmikas.
