Svabhavikakaya

Svabhavikakaya (Tib. ngowo nyi ku; ngo bo nyid sku) is one of the four kayas of a buddha.

Khenpo Pema Vajra says:

“The svabhavikakaya, is defined as the aspect of enlightened form that is distinguished by two-fold purity, the natural purity of basic space of reality and the purification of all temporary stains.”

It is the ultimate buddha kaya. Its wisdom aspect is called the wisdom dharmakaya. And its appearance as a form kaya complete with fivefold certainty in the perception of pure beings is the sambhogakaya. Its appearance as a form kaya to impure beings is the nirmanakaya.
