There are three statements in the Gita. i) The world is in Me, ii) I am not in the world and iii) The world is also not in Me (Matsthani sarva bhutani, na chaham teshvavasthitah, na cha matsthani bhutaani, nattvaham teshu te mayi...). God happens to be the unimaginable boundary of the imaginary world on all sides. The area of the room is within the four walls. It is not beyond the four walls. It means it is in the control of the boundary wall. Though the area is within the boundary wall, it is not present inside the wall. The boundary wall is also not in the area of the room since the boundary wall is outside the room. We say that an island is in the sea. It means that the island is surrounded by the sea on all sides like the boundary wall. It does not mean that the sea is in the island. At the same time, when a sunk boat is immersed in the sea, we also say that the sunk boat is in the sea. The sea water is present in the sunk boat. In both cases, we have used the same type of sentence that the island or sunk boat is in the sea. There is similarity in the statement but there is difference in the situation since the sea water exists in the sunk boat and not in the island. Here, the universe is said to be in God like the island in the sea. The God is not in the world, which means that the sea water is not in the island. Hence, the case here is not the sunk boat. But, by the similarity of the construction of the sentence in both cases that both are in the sea, you may misunderstand that the island is in the sea like the sunk boat. In such case, it is negated by saying that the world is not in the God like the sunk boat in the sea. Neither the unimaginable God exists in the imaginable world to make the world also unimaginable nor the imaginable world exists in unimaginable God to make God as imaginable. If God is in the world everywhere, the difference between good and bad becomes impossible. However, this does not mean that God cannot enter the world. As a general rule, God is not in the world. But, the omnipotent God can enter the world by entering a selected human being to make the human incarnation. The process of the entry is also unimaginable since the actions of God are also unimaginable. The human incarnation remains imaginable in the external medium but becomes unimaginable in certain specific actions. Since God is not in any item of the world, every item of the world is rejected as God as said in the Veda (Neti Neti...). Every imaginable item in the world exhibits only imaginable characteristics due to absence of unimaginable God in it. At the same time, God enters the world through a selected specific human being to become human incarnation as said in the Veda (Tadevanu pravishat...) and this shows the omnipotency of God rejecting that He cannot enter the world. It is true that He did not enter the world. It is not true if you say that He cannot enter the world. The Veda says that He can enter any item in the world (Eeshaavaasyamidam...) and this statement is misunderstood as the statement meaning that He entered every item in the world. In this way, the contradiction in the statements of the Gita can be resolved.
What Christ was saying in 32AD was the same thing but in clear Western language. He said he personified Truth, as the ideal,... as the concept that is congruent to the Reality. Reality is not in him, nor accessible directly to him. Man must use his seven sense to detect the Real World and use his mind to make sense of those sensory inputs. Yet, because truth corresponds one-to-one with that external Reality, by definition, to him, the world is within too, i.e.; as the model or image of it that he preceives as Reality. Assuming that man correctly forms a model of the rReal World inside his mind, and interacts with that model, as if he is directly inter-coursing with the Real World, he is sane, and Truth, for him, is as satisfactory as would be his condition could he directly interact with the Reality. God is all there is, ie; Reality itself... the whole external existence beyond our mind is the almighty God to which all life must bow: ...Truth inside our head, is the Holy Spirit, the image of God, almighty Reality, and is present inside our mind when our thinking correctly images the TRUTH, or the picture of Reality inside our mind.
One religion says that the God is awareness. Another religion says that God is all pervading cosmic energy. Another religion says that God is light and another religion says that God is fire etc. Like this, different created items of this universe were taken as the basic real God. Hence quarrels started, which were intensified by debates. People sitting before a dining table are quarrelling with each other since one says that the vessel is gold, another says that the plate is gold, another says that the spoon is gold and another says that the tumbler is gold. This quarrel will never end because no item on the dining table is gold! Everyone is treating a particular item as gold. Treating an item as gold is totally different from the actual item to be gold. Similarly, the reality is that God is unimaginable, who is beyond this imaginable universe. The simple reason for this is that the universe is fundamentally constituted of space or volume, which is the basic subtle energy and God is beyond the space since God has no dimensions. Now you can treat any meritorious item of the creation as God based on the merits liked by you neglecting the defects. The awareness is not God because it is not all pervading. The cosmic energy is not God because it is inert. The light and fire also cannot be God for the same reason that they are inert. But any of these items can be treated as God for the sake of meditation and worship. Such worship is called as the worship of representative model (Pratika Upasana). The direct worship (Sakshat Upasana) is also possible when God enters a human being to give right direction through propagation of right spiritual knowledge. In such case also, every such human being is God and the unimaginable God exists in such every human being. The human being is only the medium of God, but such charged human being can be treated as real God like the electrified wire being treated as the electricity itself. Hence Krishna, Buddha, Jesus, Mohammad etc becomes God and there need not be any quarrel in this point also for the sake of world peace based on the harmony of religions. This fundamental concept is revealed since simultaneously it is fortunate that today there is confidence on the receiving power of the stable and steady scientific analysis of human beings.
