Can we do good to the world? In an absolute sense, no; in a relative sense, yes. No permanent or everlasting good can be done to the world; if it could be done, the world would not be this world. We may satisfy the hunger of a man, but he will be hungry again. Every pleasure may be seen to be momentary. No one can permanently cure this ever-recurring fever of pleasure and pain.

Karma Yoga. New York, 1896.

The wind of God's grace is blowing on, for ever and ever. You must spread your sail. Whenever you do anything, do it with your whole heart concentrated on it. Think day and night, "I am of the essence of that Supreme Being-Consciousness-Bliss. What fear and anxiety have I? This body, mind, and intellect are all transient, and One who is beyond these is me."
