或由一身，示現多身。謂由現化勝解想故者，本唯一身更從化心化現現多身，化心通是神境通攝。

"Or, from one body, manifesting many bodies; that is, due to the resolute conviction of manifesting magical creations": Originally there is only one body, but further, from the mind of magical creation, it emanates and displays many bodies; this supernormal power of the mind of magical creation is subsumed under the supernormal power of psychic transformation (ṛddhi-sākṣātkriyā-abhijñā).
