摩訶止觀 2.130

2.130

As for the specific aspects, there are three kinds of bodies: first, the physical body; second, the Dharma-door body; and third, the body of true reality. If one discusses their return in terms of the cessation of transformation: the physical body returns to vimokṣa, the Dharma-door body returns to prajñā, and the body of true reality returns to the dharmakāya.
