Nine yānas
The Nyingma school of Tibetan Buddhism has nine yanas, a list made by combining the first type of three yanas, and adding the six classes of tantras.

2. Pratyekayāna
Mahāyāna consisting of:
3. Bodhisattvayāna
Vajrayāna, consisting of:
Outer Tantras
4. Kriyatantra
5. Upatantra (Tibetan spyod rgyud) ‘practice tantra’ and the Ubhayatantra (gnyis ka’i rgyud), ‘dual tantra’, because it practices the view of the next vehicle, Yogatantra, together with the action of the former.
6. Yogatantra
Inner Tantras
7. Mahāyoga
8. Anuyoga
9. Atiyoga (also Dzogchen)
It is important to note that there are numerous untranslated portions of the Vima Nyingthig, Gongpa Sangtal, etc. that place the most secret unsurpassed cycle of Menngagde as a totally independent Buddhist vehicle outside the nine yanas.
