Many people quote non-duality without understanding it really in its highest aspect.+

Most people have the "I know “attitude. Unless one gives up the “I know” business he can’t get rid of the ideas "which are full of contradictions" to the Truthseeker. But those who do not want the truth do not see the contradictions and are satisfied with their accepted truth.

Your ‘I’ know attitude is blocking you from realizing the truth, which is hidden by the illusory form, time, and space.

Many people quote non-duality without understanding it really in its highest aspect. 

One who calls himself a Gnani, but whose philosophy religion and mere quoting scriptures is really by heart he thinks he is a Gnani. He does not know that what scriptures say is true or not because he is blindly accepted scriptures without verifying them and he quotes them as proof.

There are conflicting teachings in the spiritual path and one gets confused as to which is path is genuine.

People are not capable of knowing, which path is the true path because they do not know the proper test of truth.

The seeker has to realize the Self is not him but the Self is Soul. realization of the Self as the Soul is very much necessary. to find liberation from the bondage of the illusory experience of birth, life, death, and world (dualistic illusion).

The goal of the seeker is to find and realize the Self is not 'I' but the 'Self' is the Soul, which is hidden by the 'I'.

Remember:~

Brihad Upanishad says ~ “Every man says, “I know.” What does he know?

People say Aham Brahmasmi -- I am God, I am Brahman. But when Brahman is, how can "I" remain? Only Brahman remains, not I.

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 'I' as real because some Gurus have propagated the Self as the ‘I’. There is no need to convince such mindsets who refuse to accept anything other than their accepted truth. The seeker of truth accepts only the truth nothing but the truth. The truth is hidden by the ‘I’ but it is without the ‘I’.

Some Gurus in the past glorified the ‘I’ without verifying what this ‘I’ is an actuality. And the follower of that ‘I’ based teaching Got stuck with the ‘I’. 

The ‘I’ is present only when the mind is present.

The mind is present only when the universe is present.

The universe is present only when the waking is present.

If the ‘I’ is absent then the mind, the universe, the waking, is absent. 

~ It means the ‘I’, the mind, the universe, the waking, are one and the same thing.

This is very important for the seeker to know to realize the ‘I’ itself is ignorance and to overcome the ignorance they have to discard ‘I’.

Then why use the word ‘I’ for the ‘Self’, which is the cause of ignorance.

The Soul, the Self is God in truth. It is not “I AM GOD, but it’s correct to say ‘the SELF IS GOD because the Self is not the ‘I’ or ’I AM”. : ~ Santthosh Kumaar
