Śyāmasundara: As the different parts of the body have different types of activities, so the social orders and spiritual orders also have different types of activities in terms of their qualification and position. The target of these activities, however, is always the Supreme Personality of Godhead. As it is confirmed in the Bhagavad-gītā, 'He is the supreme enjoyer.' So whether one is a brāhmaṇa or a śūdra, he has to satisfy the Supreme Lord by his activities. This is also confirmed in the Śrīmad-Bhāgavatam by a verse which reads, 'Everyone must be engaged in his particular duty, but the perfection of such work should be tested by how far the Lord is satisfied with such activities.' The injunction herein is that one has to act according to his position, and by such activities, one must either satisfy the Supreme Personality or else fall down from his position." It's so clear.
Prabhupāda: Hm?
Śyāmasundara: It's so clear, this book.
Prabhupāda: You read regularly, Nectar of Devotion, regularly. All these books should be regularly read. That will give you guidance. You haven't got to ask repeatedly to me; everything is there.
