స్వామి శివానంద సూక్తి

Words are nothing but the outward expressions of thoughts which are imperceptible. Actions are caused by feelings of desire and aversion (likes and dislikes). These feelings are caused by the fact that you attribute a pleasurable or painful nature to objects. Thought is finite. It is inadequate to express even temporal processes, not to speak of the absolute which is inexpressible. The body with its organs is no other than the mind.
