God alone is eternal, everything else is transitory. Everything dies; the angels die, men die, animals die, earths die, sun, moon, and stars, all die; everything undergoes constant change. The mountains of today were the oceans of yesterday and will be oceans tomorrow. Everything is in a state of flux. The whole universe is a mass of change. But there is One who never changes, and that is God; and the nearer we get to Him, the less will be the change for us, the less will nature be able to work on us; and when we reach Him, and stand with Him, we shall conquer nature, we shall be masters of phenomena of nature, and they will have no effect on us.
- Swami Vivekananda
