To realize the spirit as spirit is practical religion. Everything else is good so far as it leads to this one grand idea. That realization is to be attained by renunciation, by meditation-renunciation of all the senses, cutting the knots, the chains that bind us down to matter.
Swami VivekanandaNever producing pain by thought, word, and deed, in any living being, is what is called Ahimsรข, non-injury.
Swami VivekanandaIt is too often believed that a person in his progress towards perfection passes from error to truth; that when he passes on from one thought to another, he must necessarily reject the first. But no error can lead to truth. The soul passing through its different stages goes from truth to truth, and each stage is true; it goes from lower truth to higher truth.
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.
