Lord Brahmā said: O my Lord, today, after many, many years of penance, I have come to know about You. Oh, how unfortunate the embodied living entities are that they are unable to know Your personality! My Lord, You are the only knowable object because there is nothing supreme beyond You. If there is anything supposedly superior to You, it is not the Absolute. You exist as the Supreme by exhibiting the creative energy of matter.
