Man cannot see God because God is prior to anything that exists.+

Brihadaranyaka Upanishad: ~ Brahman (God in truth) is present in the form of the Athma, and it is indeed Athma itself. 

Even Rig Veda: ~ The Atman (consciousness) is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman, the Self. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5) 

Brihadaranyaka Upanishad declares: "He who worships the deities as entities entirely separate from the Self does not know the truth. For the Gods, he is like a pasu (beast)". (1. 4. 10) 

The invisible Soul is the Self. The invisible Soul, the Self, is God in truth. The invisible Soul, the Self, remains in its own awareness, which we identify as deep sleep in the waking experience.

The waking state is the state of ignorance. When ignorance vanishes, then the invisible Soul remains in its own awareness in the midst of duality (waking).

Man cannot see God (Spirit) because man and the world in which he exists are the product of ignorance. Man cannot see God because God is prior to anything that exists.

When God is present, then man and his world are absent. When man and his world are present, then God is absent.  

God is beyond form, time, and space. God is beyond form, time, and space means God is beyond the ‘I’.

You cannot imagine. You will not succeed in bringing God because God is prior to the appearance of form, time, and space (I). The nature of God is a formless, timeless, and spaceless existence.

God is beyond the bounds of the ‘I’. If you say ‘I’, you will miss God because God is hidden by the ‘I’.

You are stubborn; you still hold the Self as ‘I’ because your Guru has injected it. Remember, the ‘I’ is blocking you from realizing the Self, which is the Soul, the real God.

You are stuck to the ‘I’ by saying ‘I AM THAT’. The Self is not an individual to identify the Self as ‘I AM’. How can you identify the Self as ‘I AM’ when the Self is f formless, timeless, and spaceless existence?

People say Aham Brahmasmi -- I am God, I am Brahman. I AM THAT, but when Brahman is, how can 'I' remain? Only Brahman remains, not the I.

People think the ‘I’ without the body is the Self. The seeker has to realize that ‘I’ is not the Self, but the Self is the invisible Soul, which is the cause of the ‘I’.

That is why Ashtavakra Gita 16:10:~ If you desire liberation, but you still say 'I', if you feel the Self is the ‘I’, you are not a wise man or a seeker. You are simply a man who suffers.:~Santthosh Kumaar
