This is the principle of Universal Brotherhood of man with one another, with all life down to the little ants.
Swami VivekanandaWherever there is evil and wherever there is ignorance and want of knowledge, I have found out by experience that all evil comes, as our scriptures say, relying upon differences, and that all good comes from faith in equality, in the underlying sameness and oneness of things. This is the great Vedantic ideal.
Swami VivekanandaChrist said, "Resist not evil", and we do not understand it until we discover that it is not only moral but actually the best policy, for anger is loss of energy to the man who displays it. You should not allow your minds to come into those brain-combinations of anger and hatred.
Swami Vivekananda
