The greatest force is derived from the power of thought. The finer the element, the more powerful it is. The silent power of thought influences people even at a distance, because mind is one as well as many. The universe is a cobweb; minds are spiders.
Swami VivekanandaIf there is no strength in body and mind, the Atman cannot be realized. First you have to build the body by good nutritious food-then only will the mind be strong.
Swami VivekanandaAdvance like a hero. Do not be thwarted by anything. How many days will this body last, with its happiness and misery? When you have the human body, then rouse the Atman within and say-I have reached the state of fearlessness!...and then as long as the body endures, speak unto others this message of fearlessness: 'Thou art That', 'Arise, awake, and stop not till the goal is reached'
Swami Vivekananda
