Wisdom on Evil by Swami Vivekenanda

“Suppose there is an evil: denouncing it will not remove it, but you must go to work at the root. First, find out the cause, then remove it, and the effect will be removed also. Mere outcry will not produce any result, unless indeed it produces misfortune.
There are others who have sympathy in their hearts and who understand the idea that we must go deep into the cause. These are the great saints. One fact you must remember: all the great teachers of the world have declared that they came not to destroy but to fulfil…
We must direct our energies towards the truth, and fulfil the truth that exists, not try to make new truths.
He who sees in this world of manifoldness that One running through all; in this world of death, he who finds that one infinite Life; and in this world of in sentience and ignorance, he who finds one Light and Knowledge – unto him belongs eternal peace, unto none else, unto none else.”
(Swami Vivekenanda: Jnana-Yoga).
