I am combination of matter and spirit; so far my body is concerned, there is division. But when I come to Krsna consciousness, it is not like that. That is simply for everyone. Either he's externally a brahmana, ksatriya, vaisya, sudra, American, Indian, black, white, it doesn't matter. That is bodily. When you come to the spiritual platform, that is one. Because spirit is one... Then the business is also one - to serve Krsna; that is spiritual.
