If we want to see God, so let us hear first of all the sound vibration, because that is the beginning. In the Bible also it is said: "The Lord said, 'Let there be creation,' and there was creation." So "Let there be creation," this is sound, transcendental sound. So one who says this word, "Let there be creation," He is not within the creation. Because He, God, is speaking, "Let there be creation" means He is existing before creation.
So God is not within the creation. In the Vedic literature, therefore, description of God's body is given as sac-cid-ānanda-vigrahaḥ. Vigraha means form. Sac-cid-ānanda vigrahaḥ. Isvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1). He is not formless. He has got His form, but it is a different form. How we can understand?
Because we have got experience of this material world. We cannot see anything subtle. Gross things we can see. Therefore we can understand by our thoughts what kind of form God has got. Sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Sat means eternal, cit means knowledge and ānanda means blissful.
So if we compare with our body, then we can understand what is sac-cid-ānanda-vigrahaḥ. Sat means eternal. So if we compare with our body, this body is not eternal; it is destructible. It has got a history: it is produced at a certain period, it exists for a certain period, it grows, it gives some by-product, then it becomes older and older, and then vanquished—no more. That is our practical experience, we know. But God's body is eternal. Therefore He hasn't got a body like this. This body is not eternal—everyone can understand—but His body is eternal.
Another symptom, sat, cit. Cit means knowledge. So we have got also knowledge, but not full knowledge. That has been described in the beginning of Śrīmad-Bhāgavatam, what is the nature of God. Nature of God is described, janmādy asya yataḥ (SB 1.1.1). Nature of God means He is the supreme source of everything. Whatever, janma . . . janmādy asya. Janma ādi. Ādi means "Beginning with janma."
Just like I have already described, my body, your body, has a history of janma, or birth, a date of birth. So janma ādi means birth and sustenance and death. We have got this body produced, or born, at a certain date. It keeps, sustains, for a certain period—say fifty years, sixty years or a hundred years, utmost—and then again it is destroyed.
Therefore janma ādi means birth is also coming from Him, maintained also by Him, and when it is destroyed, it goes unto Him. That is called janma ādi, means birth, maintenance and annihilation. Janmādy asya. All this material world, they are undergoing the same process: janma, sustenance and end. Everything. This universe also is like that, everything, even the ant's body or my body, your body, elephant's body, or there are many demigods' body. Just like we have learned from Bhagavad-gītā, Brahmā's body, it keeps for millions and millions of years. One day we cannot calculate.
