Existence of God
The earth is not rotating by itself. Then why the fan is also not rotating by itself? As the invisible current is rotating the fan, the invisible God is rotating the earth. The rotation of earth is work of God. The earth is also the work of God. The rotation of fan is work. The fan is matter. Matter is a form of energy. Energy is work. Therefore the fan is also a form of work only. Thus everything is dynamism (work) only. The dynamo is God. You will immediately say that the dynamo is matter, matter is energy and since work is energy, dynamo is also a form of work. Then you will say God is also a form of work. This is the problem with the simile for God. Every simile is only a part of the creation and cannot stand as a perfect representation of the creator. God is beyond the concepts of work and no work because God is unimaginable.
You can infer the existence of God through this entire wonderful creation (work). But you cannot experience directly unless He enters a particular form of His work which is a human body like Rama, Krishna etc. You can infer the engineer by seeing the wonderful building constructed by him which is his work. But he is present only in a small room of that building. If you want to have a direct contact with him, you should search the room in which he is present. Since the whole building is his construction only, if you sit in some vacant room and try to talk with him, he will not speak to you. You have to identify that specific room in which he is present. In searching for the engineer you may find some other person in some room and can mistake him also as the engineer. Therefore you must have the knowledge of his identification.
