Change 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.
Swami VivekanandaThe greatest sin is to think that you are weak. No one is greater: realize that you are Brahman. Nothing has power except what you give it.
Swami Vivekananda
