A supreme nirmanakaya (Skt. uttamanirmāṇakāya; Tib. མཆོག་གི་སྤྲུལ་སྐུ་, Wyl. mchog gi sprul sku) is a buddha who takes birth into the world, displays the twelve deeds of a buddha, and passes into parinirvana at the end of his life. Buddha Kashyapa, Buddha Shakyamuni and the Six Munis are examples of supreme nirmanakaya buddhas.
