Krsna was acting as a ksatriya. In His boyhood, He was acting like a vaisya. But Krsna is neither ksatriya nor, nor brahmana. This is the example. He was a cowherd boy. That is business of vaisya. And when He was fighting in the battlefield, He was a ksatriya. He was marrying as a ksatriya. So although He was acting sometimes as ksatriya, sometimes as vaisya, but He's neither of these. So devotee is like that. He may act in any position, but He is above all the material conception of life. That is perfection.
