Divinity is in everyone and everywhere. You may not see Him with your physical eye, but you can visualise Him with your inner vision. Air exists, you cannot deny this even though you cannot see it or catch it. When it is hot, you can experience coolness either by using a hand fan or an electric fan. Air has not come from the fan. But whoever uses the fan receives and feels the air. Similarly God exists like air. The intellect is the fan. If you turn it toward Atma, you get Atmananda(Atmic bliss). On the other hand, you turn it towards the body, and you get temporary bodily pleasure. For crossing the ocean of life, you cannot depend on the body which is perishable and transient. It is indeed full of dirt and filth, flesh and bones. Hence you must surrender to the Divine within. Once you have God to help you, there is nothing that you cannot achieve.
