The Supreme Personality of Godhead is not perceivable through the gross material senses. It is said that Lord Sri Krsnas name, fame, pastimes, etc., cannot be understood by material senses. Only to one who is engaged in pure devotional service under proper guidance is He revealed. As stated in Brahma-samhita (5.38):

Yet one should not conclude that because He is spread all over He has lost His personal existence. To refute such arguments, the Lord says, I am everywhere, and everything is in Me, but still I am aloof. For example, a king heads a government which is but the manifestation of the kings energy; the different governmental departments are nothing but the energies of the king, and each department is resting on the kings power. But still one cannot expect the king to be present in every department personally. That is a crude example. Similarly, all the manifestations that we see, and everything that exists, both in this material world and in the spiritual world, are resting on the energy of the Supreme Personality of Godhead. The creation takes place by the diffusion of His different energies, and, as stated in the Bhagavad-gita, He is everywhere present by His personal representation, the diffusion of His different energies.

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 Devaki, the wife of Vasudeva. To eradicate this argument, Vasudeva said, My dear Lord, it is not very wonderful that You appeared within the womb of Devaki, for the creation was also made in that way. You were lying in the Causal Ocean as Maha-Visnu, and by Your breathing, innumerable universes came into existence. Then You entered into each of the universes as Garbhodakasayi Visnu. Then again You expanded Yourself as Ksirodakasayi Visnu and entered into the heart of all living entities and entered even within the atoms. Therefore Your entrance into the womb of Devaki 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 a combination of the five gross elementsnamely 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 appear as a child in the womb of Devaki, 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 energybeing an emanation from Youcover 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 is illuminated. We can understand from Brahma-samhita 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 further stated in the Bhagavad-gita that the Lord is the support of the Brahman effulgence. 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 material qualities. Such conclusions are not mature, but are, made by the less intelligent.
