This is a Mahāyānasūtra text that contains 32 chapters, discussing the Buddhist concept of wisdom (Prajñā), the advantages of studying the text, and the possible obstacles in acquiring knowledge. It also describes the difficulties of finding a good teacher and a trained disciple (P.L. Vaidya, 1960. p. XX). This text holds immense significance in shaping the development of both the Mādhyamaka and Yogācāra schools of thought. This manuscript depicts three Padmacakras on folio 270a and another one on 270b.
