Everything progresses in waves. The march of civilization, the progression of worlds, is in waves. All human activities likewise progress in waves - art, literature, science, religion.
Swami VivekanandaAll the forces that we see in nature, such as gravitation, attraction, and repulsion, or as thought, feeling, and nervous motion - all these various forces resolve into that Prana, and the vibration of the Prana ceases. In that state it remains until the beginning of the next cycle. Prana then begins to vibrate, and that vibration acts upon the Akasha, and all these forms are thrown out in regular succession.
Swami VivekanandaUnselfishness is God. One may live on a throne, in a golden palace, and be perfectly unselfish; and then he is in God. Another may live in a hut and wear rags, and have nothing in the world; yet, if he is selfish, he is intensely merged in the world.
Swami VivekanandaNever mind failures; they are quite natural, they are the beauty of life, these failures. What would life be without them? It would not be worth having if it were not for struggles. Where would be the poetry of life? Never mind the struggles, the mistakes. I never heard a cow tell a lie, but it is only a cow-never a man. So never mind these failures, these little backslidings; hold the ideal a thousand times, and if you fail a thousand times, make the attempt once more.
Swami Vivekananda
