Such half-baked dualistic knowledge gathered from different sources is not the Advaitic wisdom of Sage Sankara.+

Some Guru propagates: ~ Consciousness is alone. There is no second here, no other. ”Just close your eyes” you can see God.

Such half-baked knowledge is hearsay knowledge based on imagination, not Advaitic wisdom. Such half-baked dualistic knowledge gathered from different sources is not the Advaitic wisdom of Sage Sankara.

A Guru who speaks of knowing Brahman within the body is thinking only of his head or heart, i.e. of his body. He is hallucinating. 

Remember this: ~ 

First, know what this God supposed to be in actuality.

If the consciousness alone then what is the use of closing the eyes.  One seeker must realize his body, his eyes, and the world in which he exists, as the consciousness.

People think that there is God and that the jivas--Souls-like them form the second, other than them. There is no such duality at all.

The ignorance is the cause of the ‘I’.

The duality is present in the form of the ‘I’.

 The ‘I’ is present in the form of the mind.

 The Mind is present in the form of the universe.

 The universe appears as waking or dream (duality) and disappears as deep sleep (nonduality).

The formless substance and witness of the appearance and disappearance of the ‘I’ is the formless Soul.

The Soul is present in the form of consciousness. Consciousness is the ultimate truth because the mind, which is present in the form of the universe, ceases to exist without consciousness.  Consciousness is the ultimate truth or Brahman or God in truth.     

The seeker has to make sure what is this ‘I’ supposed to be? The seeker has to make sure the unreal nature of the ‘I’ which comes and goes in order to realize the truth, which is beyond the form, time, and space 

That is why Bhagavad Gita: ~ “The permanent is always there, only the transient ‘I’ comes and goes. (2.18) 

The ‘I’ hides the truth of the whole. God is whole not the part. 

People think the ‘I’ without the body is the Self. The seeker has to understand the fact that ‘I’ is not the Self, but the witness of the ‘I’ is the true Self, which is eternal. 

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. 

People are stuck with the reality of the ‘I’, which they take it as real because some Gurus have propagated the Self is the ‘I’. There is no need to convince such a mindset. The seeker of truth accepts only the truth nothing but the truth. 

That is why Sage Sankara says: - VC-65. As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent Truth of the Self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman, followed by reflection, meditation and so forth, but not through perverted arguments. 

People refuse to accept anything other than their Guru's words. For them, their Gurus words are the ultimate truth. They do not accept anything else other than their accepted truth. There is no need to convince such a mindset. 

Such a mindset is not fit to acquire Self-knowledge or Brahma Gnana or Atma Gnana. The seekers of truth accept only the truth nothing but the uncontradictable truth.

Even the Bhagavad Gita says: ~ Brahmano hi pratisthaham ~ Brahman (God in truth) is considered the all-pervading consciousness, which is the basis of all the animate and inanimate entities and material. (14.27).

When Bhagavad Gita says, God is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and material then nothing has to be accepted as God other than consciousness. 

Lord Krishna says Ch ~V: ~ “Those who know the Self in truth.". The last two words (tattvataha) are usually ignored by pundits, but they make all the difference between the ordinary concept of God and the truth about God.

The dualistic worship of "God” is only for the ignorant populace. The God in truth is only Atman, the innermost Self.   In reality, there is no duality, no differentiation. Only Atman exists.

Consciousness” is the only reality and there is no second thing exist other than consciousness. The universe is nothing but consciousness because it merely an illusion created out of consciousness.   The whole universe is just an illusory play of consciousness. : ~Santthosh Kumaar
