This appears to be a shorter text related to the Sarvadurgatipariśodhana and is filled with mantras and incantations. The Sarvadurgatipariśodhana (SDP) Tantra, or The Purification of All Negative Rebirths, is a Buddhist Yoga Tantra long associated with funerary practices across various Buddhist cultures. However, like most canonical tantras, the text itself offers little practical ritual instruction. (Open Edition Journals). The SDP consists of eleven chapters. There is a puṣpikā on folio 1b, and some folios appear to be newly written or later additions.
