Five kayas

The five kayas (Skt. pañcakāya; Tib. ku nga; Wyl. sku lnga) of Mahayoga as mentioned in the practice of Narak Kong Shak:

    dharmakaya,
    sambhogakaya,
    nirmanakaya,
    vajrakaya of the unchanging natural state and
    abhisambodhikaya (or perfect kaya of complete awakening).

The vajrakaya of the unchanging natural state is the embodiment of the enlightened activity of all the buddhas and the perfect kaya of complete awakening is the embodiment of all the buddhas’ enlightened qualities.
