The infinite cosmos [universe] itself is a proof of the existence of unimaginable God. ‘Infinite’ means that the boundary of the universe is everlasting. What is the secret of this everlasting boundary? Suppose, let us say that the ocean is infinite. It means that you may travel and travel for any extent of time, you will not reach the bank of the ocean. The bank of the ocean means the land, which is different from the ocean or its water. The land, which is beyond the water, is never achieved if the ocean is infinite. If the boundary of the ocean is achieved, it means the land, which is separate from water is seen. Similarly, if the boundary of the universe is achieved, it means that the unimaginable God, who is separate from the imaginable universe is achieved. But, the boundary of the universe is never achieved. This means that something, which is beyond the cosmos or the universe, can never be achieved.
What can be beyond the universe? Only the cause or generator of the universe can be beyond the universe. From a huge lump of mud, you have created a small pot using some of the mud. Now, beyond the pot, the rest lot of mud, which is the cause of the pot, exists. If you are unable to cross the boundary of the pot, the cause of the pot, which is lump of mud, is never achieved. You can take this example to certain extent only. In this example, some part of the cause is modified into the pot and the rest of the part of the cause remains. But, in the concept [creation from God], no part of the cause is modified.
The fundamental unit of the cosmos is space, which is nothing but very subtle energy. The cause or the generator of the space must not contain the space in it. In the case of mud and pot also, the cause may be in the effect but the effect is not in the cause. The mud may be in the pot but the pot is not in the crude lump of mud. Therefore, in the concept [creation from God] also, the space cannot be in its generator. Before the creation of the space, space cannot exsit anywhere and even in its cause. If space exists in the cause, the space is already created before its creation.
This is one impossible thing. The other impossible point is that if the space is in the cause, it means that space created space. Therefore, at any cost, space should not exist in its generator. It means that the generator of the space does not have spatial dimensions. The space means spatial dimensions only. Length, width and height are the spatial dimensions and the multiple product of these three is the volume or space. Your intelligence can never imagine anything, which does not have spatial dimensions. However much your intelligence may be sharp and however much your intelligence may take time, it cannot imagine anything, which does not have volume.
Therefore, the generator of this space or cosmos is always unimaginable and exists beyond the cosmos. This is the reason for the everlasting space since its generator, which is the bank or boundary of this cosmos is never achieved by the intelligence. When intelligence itself fails, there is no possibility of the mind or senses to catch that unimaginable boundary of the cosmos, which is the unimaginable God Himself. Except this explanation, no other explanation gives satisfaction to expose the reason for the infinity of the cosmos.
God is not in the cosmos because God does not have spatial dimensions and He cannot exist in the cosmos, which has spatial dimensions.
Even if you say that the unimaginable God exists in the cosmos, it is of no use, because such God is never detected even by the sharp intelligence. It is as good as saying that God is not in the cosmos. Therefore, the Veda says that nothing in this cosmos is God, because nothing contains God. If something contains God, you can say it as God. If a wire contains current, you can say such wire as current itself. Since no imaginable item contains unimaginable God, no imaginable item can be called as God (Neti neti… Veda). Even in the case of human incarnation that contains God, God is still undetectable even by intelligence, even though you call It as God. The Veda (Tvadevanupravishat…) and the Gita (Manusheem tanum…) speak about the special entry of God in human incarnation for the purpose of preaching the spiritual knowledge to human beings with exceptional specific talent in clarifying the doubts.
Such special entry cannot be the logical entry of cause into effect during modification like mud in the pot. Such special entry is based on the desire of God and not on the logical principle of entry of worldly cause into wordly effect.
