"Do not remain in darkness, come to the light."

So everyone should try to come to the light. That is Vedic injunction, tamaso mā jyotir gamaya, means "Do not remain in darkness, come to the light." Light means knowledge, and darkness means ignorance. So every one of us now in the ignorance that we do not know "What I am." Everyone is in darkness in the concept of body. Ask anyone what you are. He will say, "I am this body. I am Mr. Such and such." "I am Indian." "I am American." This is all bodily description. And we have already discussed. This body is temporary, but I, the spirit soul, I am permanent. I have already experienced that I had my childhood body, I had my babyhood body, I had my boyhood body, youthhood body, I know it, but the bodies are no more existing, but I am existing. So therefore I am permanent, and the body is nonpermanent. Therefore it is said, nāsato vidyate bhāvaḥ: "Permanency is not there in the body." Nābhāvo vidyate sataḥ: "And there is no annihilation of the permanent or the eternal."
