And śūdra means to remain on the stage of ignorance. There are four divisions of the three modes. So when we come to the stage of becoming a devotee, that means we have already passed all these lower stages." ( Lecture on SB 1.2.19 -- Los Angeles, August 22, 1972 ) "A śūdra means he becomes disturbed. He becomes disturbed. "Oh, I have no employment. How shall I eat? Where shall I go? Where shall I live?" He has no faith in Kṛṣṇa. The brāhmaṇa has got full faith. The kṣatriya has got little less faith, the vaiśya, little less faith, and the śūdra has no faith. This is the difference."
