Swami VivekanandaNone will be able to resist truth and love and sincerity. Are you sincere? Unselfish even unto death, and loving? Then fear not, not even death.
Swami VivekanandaFirst get rid of the delusion "I am the body," then only will we want real knowledge.
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.
