One may argue that the Supreme Personality of Godhead, who creates the whole cosmic manifestation simply by His glance, cannot come within the womb of Devakī, the wife of Vasudeva. To eradicate this argument, Vasudeva said, “My dear Lord, it is not a very wonderful thing that You have appeared within the womb of Devakī, because the creation was also made in that way. You were lying in the Causal Ocean as Mahā-Viṣṇu, and by Your breathing process, innumerable universes came into existence. Then You entered into each of the universes as Garbhodakaśāyī Viṣṇu. Then again You expanded Yourself as Kṣīrodakaśāyī Viṣṇu and entered into the hearts of all living entities and even within the atoms. Therefore Your entrance into the womb of Devakī is understandable in the same way. You appear to have entered, but You are simultaneously all-pervading. We can understand Your entrance and nonentrance from material examples. The total material energy remains intact even after being divided into sixteen elements. The material body is nothing but the combination of the five gross elements—namely earth, water, fire, air and ether. Whenever there is a material body, it appears that such elements are newly created, but actually the elements are always existing outside of the body. Similarly, although You have appeared as a child in the womb of Devakī, You are also existing outside. You are always in Your abode, but still You can simultaneously expand Yourself into millions of forms.
“One has to understand Your appearance with great intelligence because the material energy is also emanating from You. You are the original source of the material energy, just as the sun is the source of the sunshine. The sunshine cannot cover the sun globe, nor can the material energy—being an emanation from You—cover You. You appear to be in the three modes of material energy, but actually the three modes of material energy cannot cover You. This is understood by the highly intellectual philosophers. In other words, although You appear to be within the material energy, You are never covered by it.”
We hear from the Vedic version that the Supreme Brahman exhibits His effulgence and therefore everything becomes illuminated. We can understand from the Brahma-saṁhitā that the brahmajyoti, or the Brahman effulgence, emanates from the body of the Supreme Lord. And from the Brahman effulgence, all creation takes place. It is also stated in the Bhagavad-gītā that the Lord is the support of the Brahman effulgence. Therefore, originally He is the root cause of everything. But persons who are less intelligent think that when the Supreme Personality of Godhead comes within this material world He accepts the material qualities. Such conclusions are not very mature but are made by the less intelligent.
The Supreme Personality of Godhead is directly and indirectly existing everywhere; He is outside this material creation, and He is also within it. He is within this material creation not only as Garbhodakaśāyī Viṣṇu; He is also within the atom. The existence of the atom is due to His presence. Nothing can be separated from His existence. In the Vedic injunctions we find that the Supreme Soul, or the root cause of everything, has to be searched out because nothing exists independently of the Supreme Soul. Therefore the material manifestation is also a transformation of His potency. Both inert matter and the living force—the soul—are emanations from Him. Only the foolish conclude that when the Supreme Lord appears He accepts the conditions of matter. Even if He appears to have accepted a material body, He is still not subjected to any material condition. Kṛṣṇa has therefore appeared and defeated all imperfect conclusions about the appearance and disappearance of the Supreme Personality of Godhead.
“My Lord, Your appearance, existence and disappearance are beyond the influence of the material qualities. Because Your Lordship is the Supreme Brahman and the controller of everything, there is nothing inconceivable or contradictory in You. As You have said, material nature works under Your superintendence, just like a government officer working under the orders of the chief executive. The influence of subordinate activities cannot affect You. Since You are the Supreme Brahman, everything is existing within You, and since all the activities of material nature are controlled by Your Lordship, none of these activities affect You.
