Everything which has name and form must die. If there are heavens with forms, these heavens must vanish in course of time; they may last millions of years, but there must come a time when they will have to go.
Swami VivekanandaDo not believe a thing because you have read about it in a book. Do not believe a thing because another man has said it was true. Do not believe in words because they are hallowed by tradition. Find out the truth for yourself. Reason it out. That is realization.
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 Vivekananda
