Bhagavad-gita As It Is
BG Chapters 13 - 18
BG 16.1-3, Purport:
Śaucam means cleanliness, not only in mind and body but in one's dealings also. It is especially meant for the mercantile people, who should not deal in the black market. Nāti-mānitā, not expecting honor, applies to the śūdras, the worker class, which are considered, according to Vedic injunctions, to be the lowest of the four classes. They should not be puffed up with unnecessary prestige or honor and should remain in their own status. It is the duty of the śūdras to offer respect to the higher class for the upkeep of the social order.
