Knowledge can only be got in one way, the way of experience; there is no other way to know.
Swami VivekanandaInfinite power of the spirit, brought to bear upon matter evolves material development, made to act upon thought evolves intellectuality, and made to act upon itself makes of man a God. First, let us be Gods, and then help other to be GOds. Be and Make. Let this be our motto.
Swami VivekanandaIf there's a God, we must see him and if there's a soul we must perceive it. Otherwise, it's better not to believe.
Swami VivekanandaThere is the mind itself. It is like a smooth lake which when struck, say by a stone, vibrates. The vibrations gather together and react on the stone, and all through the lake they will spread and be felt. The mind is like the lake; it is constantly being set in vibrations, which leave an impression on the mind; and the idea of the Ego, or personal self, the "I", is the result of these impressions. This "I" therefore is only the very rapid transmission of force and is in itself no reality.
Swami Vivekananda
