The sign of vigour, the sign of life, the sign of hope, the sign of health, the sign of everything that is good, is strength. As long as the body lives, there must be strength in the body, strength in the mind, [and strength] in the hand.
Swami VivekanandaDo you know how much energy, how many powers, how many forces, are still lurking behind that frame of yours? What scientist has known all that is in man? Millions of years have passed since man came here, and yet but one infinitesimal part of his powers has been manifested. Therefore, you must not say that you are weak. How do you know what possibilities lie behind that degradation on the surface? You know but little of that which is within you. For behind you is the ocean of infinite power and blessedness.
Swami VivekanandaAlways keep the mind cheerful. Everyone will die once. Cowards suffer the pangs of death again and again, solely due to the fear in their own minds.
Swami Vivekananda
