It will not do merely to listen to great principles. You must apply them in the practical field, turn them into constant practice. What will be the good of cramming the high - sounding dicta of the scriptures? You have first to grasp the teachings of the Shastras, and then to work them out in practical life. Do you understand? This is called practical religion.
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.
Swami Vivekananda
