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. The pagination of 188 is missed out. Fols. 125~131 (7 leaves) are missing. two folia (image 262 and 263) belonging to a Ms. of other prajñāpāramitā-sūtra (Matsunami, 1965. p. 23). These two folia are part of the post-colophon of another Prajñāpāramitā-sūtra manuscript, dated Saṃvat 970, which is probably the Nepal Saṃvat. This indicates that the second manuscript is from a later period, belonging to 1849 CE.
