Here are two Sanskrit words. The one is Pravritti, which means revolving towards, and the other is Nivritti, which means revolving away. The “revolving towards” is what we call the world, the “I and mine”; it includes all those things which are always enriching that “me” by wealth and money and power, and name and fame, and which are of a grasping nature, always tending to accumulate everything in one centre, that centre being “myself”. That is the Pravritti, the natural tendency of every human being; taking everything from everywhere and heaping it around one centre, that centre being man’s own sweet self. When this tendency begins to break, when it is Nivritti or “going away from,” then begin morality and religion. Both Pravritti and Nivritti are of the nature of work: the former is evil work, and the latter is good work.
This Nivritti is the fundamental basis of all morality and all religion, and the very perfection of it is entire self-abnegation, readiness to sacrifice mind and body and everything for another being. When a man has reached that state, he has attained to the perfection of Karma-Yoga.
This is the highest result of good works. Although a man has not studied a single system of philosophy, although he does not believe in any God, and never has believed, although he has not prayed even once in his whole life, if the simple power of good actions has brought him to that state where he is ready to give up his life and all else for others, he has arrived at the same point to which the religious man will come through his prayers and the philosopher through his knowledge; and so you may find that the philosopher, the worker, and the devotee, all meet at one point, that one point being self-abnegation. However much their systems of philosophy and religion may differ, all mankind stand in reverence and awe before the man who is ready to sacrifice himself for others. (I, 85 – 86)
