The Kulayarāja Tantra (Tibetan phonetically: Kunjed Gyalpo, Tibetan: ཀུན་བྱེད་རྒྱལ་པོའི་རྒྱུད་, Wylie: Kun-byed Rgyal-po'i Rgyud; "All-Creating King", "Supreme Source") is a Buddhist Tantra in the Tibetan language and the principal 'mind-series' (Wylie: sems sde) text of the Dzogchen tradition. The Kunjed Gyalpo contains within it smaller Dzogchen texts (from the early 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 semde literature.
