Jagadīśa: Śrīla Prabhupāda, what exactly do the... Do the vaiśyas cultivate the fields or the śūdras cultivate the fields?
Prabhupāda: Hm?
Jagadīśa: Is it the duty of the vaiśyas to cultivate the fields or...?
Prabhupāda: Actually it is the duty of the vaiśyas, but the śūdras can help everyone, the helpers. The śūdras will help the brāhmaṇas, the kṣatriyas, as well as the vaiśyas. Those who have no brain—simply they can carry out order—they are śūdras. And those who have got brain, they can act as brāhmaṇa, kṣatriya, or vaiśya. They have got brain to take the initiative. First-class brain, they should be engaged in studying śāstras, writing books and in the worship of the Deity, lecturing enlightened people. This is brāhmaṇa. They haven't got to work as kṣatriya, as vaiśya. They are simply intellectuals. This is brāhmaṇa, with good character.
