The seeker has to realize what is real by realizing our body, ego and our experience of the world are an illusion created out of the Soul, the Self.+

People think that the enlightenment is about the experience of the timeless, formless, spaceless unmanifested dimension and it is possible by transcending the ego. 

People also think that the universe was born millions of years ago and the universe erupted from the big void, from nothingness. But these ideas are mere speculation based on the false self (ego) within the false experience (waking).

Where there is experience then there is duality. Where there is duality then there is always an illusion. Where there is an illusion then there is always ignorance. Where there is ignorance there is always ego. 

Where there is ego the falsehood experienced as reality. Therefore, getting rid of the falsehood in its totality is necessary to realize the reality.

Thus, transcending ego alone one cannot get nondual reality, the whole falsehood, which is in the form of the universe has to be transcended mentally to realize the ultimate reality.

It is erroneous to say that only by transcending the ego; one is able to experience formless, timeless, and space-less unmanifested dimension. 

It is wrong to say that the universe erupted from the big void, from nothingness. All these are mere imaginations based on the false self (ego). 

Remember:~

You’re not what you see because you are not the ‘Self’. The ‘Self’ is Soul that sees the coming and going, of the world in which you exist. 

Thus, the world in which you exist is nothing but the Soul, which is present in the form of consciousness. Thus, the world in which you exist is nothing but consciousness.

One thinks the mind is within this body; whereas the body and his experience of the world are within the mind. The consciousness is hidden within the three states, but it is without the three states.

The one, that has the awareness of the three states, is not the body but the Soul which is in the form of consciousness. 

Thus, consciousness is not limited to the waking experience alone because it pervades all three states.

Until one views and judges the world-view on the base of the ego (waking entity), he is in the grip of individuality. 

The Self is not an individual because it is universal. And it pervades everything and everywhere in all the three states. Thus, individualized judgment will not lead one to the non-dual destination.

Till one thinks the mind is within the body, all the doubts and confusion will prevail. When one indulges in deeper self-search he becomes aware that the body and the world are within the mind.

It is necessary to realize that the body and the world together are the mind (I). Thus, it is necessary to investigate ‘What is this mind (I)?’, ‘What is the substance of the mind?” and ‘What is the source of the mind?’”

The seeker has to realize what is real by realizing our body, ego and our experience of the world are an illusion created out of the Soul, the Self.

The nature of the Self is emptiness. It is identified by different masters with a different name, such as Brahman, Consciousness, Self, and the Ultimate Truth.

When the Soul the ‘Self’ becomes aware of its formless non-dual nature then it becomes empty of ignorance ( illusion or duality or experience of waking or dream). 

Thus, whatever remains empty of duality or ignorance or illusion is the non-dual reality. Only through wisdom, one becomes aware of the truth in the midst of duality.

That is why Sage  Sankara said: ~ VC-63- Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation.

The universe will not remain a reality when Advaitic wisdom dawns. The universe is a mere illusion created out of consciousness and there is conscious awareness of the unity in diversity because there is no second thing exists other than consciousness. : ~ Santthosh Kumaar
