It is good to love God for hope of reward, but it is better to love God for love's sake; and the prayer goes: O Lord, I do not want wealth nor children nor learning. If it be Thy will, I shall go from birth to birth. But grant me this, that I may love thee without the hope of reward 'love' unselfishly for love's sake.
Swami VivekanandaChange is always subjective. All through evolution you find that the conquest of nature comes by change in the subject. Apply this to religion and morality, and you will find that the conquest of evil comes by the change in the subjective alone. That is how the Advaitic system gets its whole force, on the subjective side of man.
