In a traditional manner to ensure an auspicious conclusion to the collection, volume 16 and 17 contains transmissions focusing on the deities of longevity: the white Tārā, Amitāyus, and Uṣṇīṣavijayā.
As Kongtrul writes:
The ninth section of this collection contains a number of unrelated teachings—spiritual advice that derives from various traditions. These include the blessing ritual and instructions concerning the Eighty-Four Mahasiddhas; the individual empowerments and instructions for The Six Instructions of Maitripa; the cycles of Mahakarunika Chittavishramana and The Threefold Quintessential Meaning as transmitted in the Zhalu tradition; the five definitive instructions on Avalokiteshvara; Thangtong Gyalpo’s practice associated with the six-syllable mantra; the Mahamudra instructions and The Sutra Ritual of the Sage from the Bodong tradition; the instruction on chandali and the transference of consciousness transmitted by Rechen Paljor Zangpo; the “mother transference” of Rongtön; the instructions on the “seven lines of specific transmission” according to the new translations of the Jonang tradition; and various kinds of alchemical procedures.
The collection concludes in a positive manner with the authorizations for the three deities of longevity, the intimate oral lineage of the seven-day longevity sadhana, the instructions for the longevity practice of White Tara according to the tradition of Bari Lotsawa, and a ritual to honor the three deities of longevity.
Volume 16 entitled, "Mahasiddha Practice," is available now and Volume 17, the continuation of Kongtrul's compilation of miscellaneous instructions will be released soon.
