Truth or Reality is not out there. The object of your perception or experience may be outside, but do you perceive or feel your feeling or perception outside? It is all inside. It is your consciousness inside that interprets what is perceived. Sages see the world inside of them. Sages experience the whole existence inside of them. To them the Reality is inside. When you become conscious of Consciousness, you rise from mundane to magnificence. Mind becomes a still lake reflecting the Divine in all of existence. This is state of Nirvana we are born to reach in this very birth. 
Light and Love!
