In the beginning was the word, that means before the creation there was the transcendental sound. So that word, or transcendental sound, is not like the material sound. If we associate with the transcendental sound Hare Kṛṣṇa, then we become purified to become transcendental. Just like we can have a crude example—you take one iron rod and put into the fire. The iron rod will be warm, warmer, and gradually it will be red hot. When it is red hot, then it is no longer the iron rod; it is fire. So how it has become fire? By association with the fire. Simply, therefore, if you simply keep yourself touch with God by this vibration of transcendental sound, gradually you become godly. So as soon as you become godly, you become the same quality—aiśvaryasya samagrasya (Viṣṇu Purāṇa 6.5.47): full riches, full power, full strength, full knowledge, everything full. Therefore the Vedic instruction is tamasi mā jyotir gamaḥ: "Don't keep yourself in darkness. Come to the light."
So our only request is at the present moment, the whole world is for want of godly understanding. They are in darkness. So our duty is, when we have got this privilege of this human form of life, we should not keep ourself in darkness. Darkness means without any knowledge of the soul and God. So long I am thinking that, "I am this body," it is in darkness. Except the human being, any other living being, they are all in darkness. Therefore human being's business is not to keep himself in darkness, but come to the light.
