Kulayarāja Tantra
The Kulayarāja Tantra (Tibetan phonetically: Kunjed Gyalpo, Tibetan: ཀུན་བྱེད་རྒྱལ་པོའི་རྒྱུད་, Wylie: Kun-byed Rgyal-po'i Rgyud; English: "All-Creating King", or "Supreme Source") is a Buddhist Tantra in the Tibetan language and the principal Mind Series (Wylie: sems sde) text of the Dzogchen (Great Perfection) tradition of the Nyingma school. The Kunjed Gyalpo contains within it smaller Dzogchen texts (from the earlier 18 semde texts) such as the Cuckoo of Rigpa (Rig pa'i khu byug) which appears in the thirty first chapter, as such it appears to be a sort of compilation of earlier Dzogchen literature (which is now categorized as "semde").
