What is "kukuraja"

Kukuraja was a mahasiddha within the lineages of Esoteric Buddhism and he was contemporaneous with Indrabhuti of Sahor in Oddiyana (also known as King Ja) and Kambalapada (also known as Lawapa).

Some sources hold that it was Kukuraja who prophesied the birth of Garab Dorje, the founder of the human lineage of the Nyingmapa Dzogchen Tantra teachings though the chronology is problematic. The tradition holds that there may be multiple Kukaraja's which are conflated (a view also propounded by modern scholarship) or the different Kukkaraja according to Nyingma tradition may be understood as a lineage of mindstream emanations.
