Three lineages of transmission
from the dharmakaya Samantabhadra to the sambhogakaya buddhas in the Akanishtha heaven, such as the buddhas of the five families, and Vajrasattva, and then to nirmanakaya buddhas such as the twelve teachers.
- the sign transmission of the vidyadharas (Tib. rigdzin da gyü; Wyl. rig 'dzin brda brgyud): from Vajrasattva to the first human Dzogchen master Garab Dorje, through to Padmasambhava. For the Dzogchen lineage, this includes masters such as Mañjushrimitra, Shri Singha, and Jñanasutra.
- the oral transmission from special individuals (Tib. gangzak nyen gyü; Wyl. gang zag snyan brgyud).
- the mind-to-mind transmission by victorious ones
- the transmission through symbols by masters of awareness
- the oral transmission by human individuals
