In the Chokling's Zabtik Drolma it is said that the outer level is kriya yoga, the inner is yoga tantra and the secret is annutaratantra. The last is quite strange for a terma cycle but the description of the practices involved in the secret cycle seem to cover more or less cover mahayoga, anuyoga and atiyoga but it is still said to be annutaratantra.conebeckham wrote: But here's an example: Check out Chogyur Lingpa's Zabtik Drolma. That cycle should be familiar to lots of us, right? So, the outer practice, which is what most of us know, is the 4 mandala offering to the 21 Taras, popular in most Kagyu centers, and I believe some Nyingma centers too.
The inner practice relates to the 8 Taras who protect from the 8 fears, and these relate to Inner Afflictions, as well..and they are visualized internally, rather than externally.
The secret practice, If I recall, relates to Tara and Hayagriva, Yabyum.
