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.
