No duty is ugly, no duty is impure. (I. 70)
Each duty has its own place, and according to the circumstances in which we are placed, we must perform our duties. (I. 47)
Duty for duty's sake, work for work's sake.
Duty is seldom sweet.
Our duty is to encourage every one in his struggle to live up to his own highest ideal, and strive at the same time to make the ideal as near as possible to the Truth.
All our duties are His.
Ours are the duties. Let the fruits take care of themselves.
Every duty is holy, and devotion to duty is the highest form of the worship of God; it is certainly a source of great help in enlightening and emancipating the deluded and ignorant - encumbered souls of the bound ones.
