Question: Can prasad [blessed food] affect the physical?
Sri Chinmoy: Prasad affects the physical if the physical also aspires along with the psychic or spiritual in us. If the spiritual in us is followed by the physical, or if the physical aspires along with the spiritual, then definitely the prasad will give benefit to the physical consciousness as well.
