There is to be found in every religion the manifestation of this struggle towards freedom. It is the groundwork of all morality,of unselfishness, which means getting rid of the idea that men are the same as their little body. When we see a man doing good work, helping others, it means that he cannot be confined within the limited circle of “me and mine”. There is no limit to this getting out of selfishness. All the great systems of ethics preach absolute unselfishness as the goal. Supposing this absolute unselfishness can be reached by a man,what becomes of him? He is no more the little Mr. So – and -so; he has acquired infinite expansion. The little personality which he had before is now lost to him for ever; he has become infinite, and the attainment of this infinite expansion is indeed the goal of all religions and of all moral and philosophical teachings. The personalist, when he hears this idea philosophically put, gets frightened. At the same time, if he preaches morality, he after all teaches the very same idea himself. He puts no limit to the unselfishness of man. Suppose a man becomes perfectly unselfish under the personalistic system, how are we to distinguish him from the perfected ones in other systems? He has become one with the universe and to become that is the goal of all; only the poor personalist has not the courage to follow out his own reasoning to its right conclusion. Karma-Yoga is the attaining through unselfish work of that freedom which is the goal of all human nature. Every selfish action, therefore, retards our reaching the goal, and every unselfish action takes us towards the goal; that is why the only definition that can be given of morality is this: That which is selfish is immoral, and that which is unselfish is moral.
