The first sign that you are becoming religious is that you are becoming cheerful. When a man is gloomy, that may be dyspepsia, but it is not religion. Misery is caused by sin, and by no other cause. What business have you with clouded faces? It is terrible. If you have a clouded face, do not go out that day, shut yourself up in your room. What right have you to carry this disease out into the world?
Swami VivekanandaThis is a great fact: strength is life; weakness is death. Strength is felicity, life eternal, immortal; weakness is constant strain and misery, weakness is death.
Swami VivekanandaExcepting the infinite spirit, everything else is changing. There is the whirl of change.
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 Vivekananda
