Knowledge is inherent in man; no knowledge comes from outside; it is all inside. We say Newton discovered gravitation. Was it sitting anywhere waiting for him? It was in his own mind; the time came and he found it out. All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in our own mind. The external world is simply the suggestion, the occasion, which sets you to study your own mind.
Swami VivekanandaHe who is alone is happy. Do good to all, like everyone, but do not love anyone. It is a bondage, and bondage brings only misery. Live alone in your mind - that is happiness. To have nobody to care for and never minding who cares for one is the way to be free.
Swami VivekanandaLet me die fighting. Two years of physical suffering have taken from me twenty years of life. But the soul changes not, does it? It is there, the same madcap - Atman - mad upon one idea, intent and intense.
Swami Vivekananda
