The brahmanas and Vedic knowledge come from the mouth of the Supreme Personality of Godhead, the ksatriyas and bodily strength come from His arms, the vaisyas and their expert knowledge in productivity and wealth come from His thighs, and the sudras, who are outside of Vedic knowledge, come from His feet. May that Supreme Personality of Godhead, who is full in prowess, be pleased with us.
