Brahmā addressed Lord Kṛṣṇa as Acyuta because the Lord is never forgetful of a little service rendered by His devotee. He is so kind and affectionate toward His devotees that a little service by them is accepted by Him as a great deal. Brahmā has certainly rendered much service to the Lord. As the supreme personality in charge of this particular universe, he is, without a doubt, a faithful servant of Kṛṣṇa; therefore he could appease Kṛṣṇa. He asked that the Lord understand him as a subordinate servant whose little mistake and impudence might be excused. He admitted that he was puffed up by his powerful position as Lord Brahmā. Because he is the qualitative incarnation of the mode of passion within this material world, this was natural for him, and therefore he committed the mistake. But Lord Brahmā hoped that since he was, after all, Lord Kṛṣṇa's subordinate, the Lord would kindly take compassion upon him and excuse him for his gross mistake.
Lord Brahmā realized his actual position. He is certainly the supreme teacher of this universe, in charge of the production of material nature, consisting of the complete material energy, false ego, sky, air, fire, water and earth. Such a universe may be gigantic, but it can be measured, just as we measure our body as seven spans. Generally everyone's personal bodily measurement is calculated to be seven spans of his hand. This particular universe may appear as a very gigantic body, but it is nothing but the measurement of seven spans for Lord Brahmā. Aside from this universe, there are unlimited other universes which are outside the jurisdiction of this particular Lord Brahmā. Just as innumerable atomic infinitesimal fragments pass through the holes of a screened window, so millions and trillions of universes in their seedling form are coming out from the bodily pores of Mahā-Viṣṇu, and that Mahā-Viṣṇu is but a part of a part of the plenary expansion of Kṛṣṇa. Under these circumstances, although Lord Brahmā is the supreme creature within this universe, what is his importance in the presence of Lord Kṛṣṇa?
Lord Brahmā therefore compared himself to a little child within the womb of his mother. If the child within the womb plays with his hands and legs, and while playing touches the body of the mother, is the mother offended with the child? Of course she isn’t. Similarly, Lord Brahmā may be a very great personality, and yet not only Brahmā but everything that be is existing within the womb of the Supreme Personality of Godhead. The Lord's energy is all-pervading: there is no place in the creation where it is not acting. Since everything is existing within the energy of the Lord, the Brahmā of this universe and the Brahmās of the many other millions and trillions of universes are existing within the energy of the Lord; therefore the Lord is considered to be the mother, and everything existing within the womb of the mother is considered to be the child. And the good mother is never offended with the child, even if he touches the body of the mother by kicking his legs.
