Within the indigenous Tibetan literature, a very large number of Aparimitāyur­jñāna sādhanas have been created over the centuries within all the lineages and schools. The Nyingma tradition of rediscovered treasure texts (gter ma), too, has produced many Aparimitāyur­jñāna revelations, from Nyangral Nyima Ozer (nyang ral nyi ma ’od zer, 1136–1204) onward. The importance that Aparimitāyur­jñāna assumed in tantric practice may be one of the reasons why this Aparimitāyur­jñānasūtra was classified within most Kangyurs as a tantra rather than as a sūtra.
