Although Lord Rsabhadeva knew everything about confidential Vedic knowledge, which includes information about all types of occupational duties, He still maintained Himself as a ksatriya and followed the instructions of the brahmanas as they related to mind control, sense control, tolerance and so forth. Thus He ruled the people according to the system of varnasrama-dharma, which enjoins that the brahmanas instruct the ksatriyas and the ksatriyas administer to the state through the vaisyas and sudras.
