Natural nirmanakaya
Natural nirmanakaya (Tib. རང་བཞིན་སྤྲུལ་པའི་སྐུ་, Wyl. rang bzhin sprul pa'i sku) or nature nirmanakaya, is also called 'reflection sambhogakaya' (གཟུགས་བརྙན་ལོངས་སྐུ, gzugs brnyan longs sku), or semi-nirmanakaya semi-sambhogakaya (ཕྱེད་སྤྲུལ་ལོངས་སྐུ, phyed sprul longs sku) in the Nyingma teachings. ‘Natural’ or ‘nature’ refers to the cognizant nature, which manifests as sambhogakaya at the level of the path.
