Tapihritsa or Tapahritsa (c 7th ~ 8th century) was a Bon practitioner who achieved the Dzogchen mastery of the rainbow body and consequently, as a fully realised trikaya Buddha, is invoked as an iṣṭadevatā (Classical Tibetan: yi dam) by Dzogchen practitioners in both Bon[1] and Tibetan Buddhism.
[3][4] The historical Tapihritsa was born in Zhangzhung to a family of nomads.
[4] Tapihritsa was contemporaneous with Ligmincha, King of Zhangzhung, and Trisong Detsen, Emperor of Tibet.
[4] Tapihritsa is often visualized as representing the realization of all the masters of the Zhangzhung Whispered Transmission (Wylie: zhang zhung snyan brgyud) lineage, one of the three Bon Dzogchen lineages.
[citation needed] Tapihritsa's primary notable work is The Twenty-One Nails (rdzogs pa chen po zhang zhung snyan rgyud las gzer bu gnyis shu rtsa gcig).
