God told a certain sannyâsî: "Do not worry, I am always behind you." One day, the sannyâsî wanted to test whether God spoke the truth. So, acting out of doubt, he quickly turned his head and naturally, did not see God. He asked God why He wasn't there and God said: "As you turned your head, I moved around to the back of your head! Naturally, you were unable to see Me".
God is Truth. Truth is His Nature. Truth is His sign, His breath.
