Taishō Tripiṭaka
The "Tattvasiddhi Śāstra" ("the treatise that accomplishes reality"; Chinese: 成實論, "Chéngshílun"), is an extant Abhidharma text which was popular in Chinese Buddhism. This Abhidharma is now contained in the Chinese Buddhist canon, in sixteen fascicles (Taishō Tripiṭaka 1646). Its authorship is attributed to Harivarman, a third-century monk from central India. This work may belong to the Mahāsāṃghika Bahuśrutīya school or to the Sautrāntika school.
