Very appreciate the author who has summarized the Buddhas forms, the Dharmakaya, the Sambhogakaya, and Nirmanakaya. The Nirmanakaya is the form the samsara beings like us, the wordly gods, the spirits, the animals can see. Even in Nirmanakaya appearing as a worldly god, for us human, we cannot perceive them. Only when they emanate in human form then we can see them directly. However in a human form, without much knowledge ourselves, can we know they are of enlightened mind?
