The seeker has to make sure of the unreal nature of the ‘I’, which appears and disappears in order to realize the truth, hidden ignorance.+

Most of the Gurus' and Yogis' approach was more practical, and they stuck with the reality of the 'I', they take it as real.

All their teachings of Advaita are based on the dualistic perspective. They describe marvelously the goal but do not indicate the steps to be taken: their recurring phrases "unified consciousness" and "let go" and "'love alone" are not a roadmap. Such teaching will not yield the truth of the whole.

Many Gurus describe perfection is the awakening to Reality ~the realization that pure Consciousness alone is, that the perpetually fluctuating and evanescent contents of the mind derive from it. This awakening effectively happens in an instant. But in order for the lightning flash to take place, resulting in a firm and unshakable certitude, long labor is necessary, which they seem to underestimate. “Truth is formless is their answer.

Many Guru's teaching seems essentially negative, potent but bitter medicine for those imprisoned by institutional cults. They break the disciple's bonds but then lead him to a vast desert where they abandon him.

The ‘I’ is blocking your realization of truth. The ‘I’ based teachings have to be discarded in order to realize the Advaitic reality.

The seeker has to make sure what is this ‘I’ supposed to be in actuality? The seeker has to make sure of the unreal nature of the ‘I’, which appears and disappears in order to realize the truth,  hidden ignorance.

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 Soul.

Where there is ‘I’ there is ignorance.

Where there is ignorance there is separation.

Where there is a separation there is duality.

Where there is duality there is an illusion.

Where there is an illusion there is the mind.

Where there is the mind there is the universe.

Where there is the universe there is waking or dream.

Where there is the universe there is waking or dream there is form, time, and space.

But remember:~

Where there is no ‘I’ there is no ignorance.

Where there is no ignorance there is no separation.

Where there is no separation there is no duality.

Where there is no duality there is an illusion.

Where there is no illusion there is no mind.

Where there is no mind there is no universe.

Where there is no universe there is no waking or dream.

Where there is no waking or dream there is no form, time, and space

When there are no divisions of form, time, and space, there is the Advaitic reality.

Perfect understanding of ‘what is what' leads to the realization of Advaitic truth, which is hidden by the illusory form, time, and space. :~ Santthosh Kumaar
