That the Supreme Lord, the Personality of Godhead, is all-perfect is confirmed in all śruti-mantras. It is said in the śruti-mantras that the all-perfect Lord glanced over matter and thus created all living beings. The living beings are parts and parcels of the Lord, and He impregnates the vast material nature with the seeds of the spiritual sparks. Thus the creative energies are set in motion for so many wonderful creations. When one atheist argued that God is no more expert than the manufacturer of a subtle watch that has so many delicate parts, we had to reply that God is a greater mechanic than the watchmaker because He creates one machine in male and female forms that go on producing innumerable similar machines without the further attention of God. If a man could manufacture a set of machines capable of producing other machines without the man giving the matter any further attention, then that man could be said to equal the intelligence of God. But that is not possible. Each and every one of man's imperfect machines has to be handled individually by a mechanic. Because no one can be equal to God in intelligence, another name for God is asamaurdhva, which indicates that no one is equal to or greater than Him. Everyone has his intellectual equal and superior, and no one can claim that he has neither. But this is not the case with the Lord. The śruti-mantras indicate that before the creation of the material universe there existed the Lord, who is the master of everyone. It was the Lord who instructed Brahmā in Vedic knowledge. That Personality of Godhead has to be obeyed in all respects. Anyone who wants to become freed from material entanglement must surrender unto Him, and this is confirmed in the Bhagavad-gītā.
Unless one surrenders unto the lotus feet of the Personality of Godhead, it is sure and certain that one will be bewildered, even if he happens to be a great mind. Only when great minds surrender unto the lotus feet of Vāsudeva and know fully that Vāsudeva is the cause of all causes, as confirmed in the Bhagavad-gītā (7.19), can they become mahātmās, or the truly broad-minded. But such broad-minded mahātmās are rarely seen. Only they, however, can understand that the Supreme Lord, the absolute Personality of Godhead, is the primeval cause of all creations. He is the ultimate (parama) truth because all other truths are dependent on Him. And because He is the source of everyone's knowledge, He is omniscient; there is no illusion for Him, as there is for the relative knower.
