The 'I-centric' knowledge is not the Advaitic wisdom of Sage Sankara.+

Sages of truth restrained themselves parting the Self-knowledge or Brahma Gnana or Atma Gnana to the mass and only a selected few.

Self-knowledge or Brahma Gnana or Atma Gnana was hidden from the people who were not qualified and receptive to it. Self-knowledge or Brahma Gnana or Atma Gnana was not written down but was imparted orally to the chosen few. 

Thus, religion was given to the ignorant populace and the knowledge of the Spirit or God in truth is given to only a selected few.

Bhagavad Gita says: ~ Among thousands of men, scarcely one strives for perfection; and of those who strive and succeed, scarcely one knows the ‘Self’ in truth.

The path of wisdom attracts only those who are in search of truth and they appreciate it greatly.   The ignorant are not spiritually mature the receive Self-knowledge or Brahma Gnana or Atma Gnana.  The ignorant indulge in argument and provocation and personal attack, which hinders their own realization of the ultimate truth or Brahman.

From the Advaitic perspective, the ‘I’-centric’ knowledge is mental garbage.

If ‘I’ is present then only there is ignorance. 

If ignorance is there then only there is duality.

If there is duality then only the mind is present.

If the mind is present then only form, time, and space are present. 

If form, time, and space are present then only the universe is present.

If the universe is present then only the waking is present.

If the waking is present then only the individual experience of birth, life, death, and the world is experienced as a reality.

If the ‘I’ is absent then: ~

If ‘I’ is absent then only there is no ignorance. 

If ignorance is absent then there is no duality.

If there is no duality then the mind is absent.

If the mind is absent then form, time, and space are absent. 

If form, time, and space are absent then the universe is absent.

If the universe is absent then the waking experience is absent.  

If the waking is absent then only the individual experience of birth, life, death, and the world is an illusion.

Without the illusion, the Soul, the Self alone prevails as the ultimate reality or Brahman or God.

Through Self-knowledge or Brahma Gnana or Atma Gnana, the seeker will be able to mentally observe the Soul, the Self as it is in the midst of the dualistic illusion by realizing that form, time and space are one in essence.

This is your bondage that you are stuck up to the ‘I’ centric Gurus and their teaching.  ‘I’ centric teachings are lower knowledge meant for lower stages. 

The 'I-centric' knowledge is not the Advaitic wisdom of Sage  Sankara. 

The seeker has to ignore these ‘I’ based teaching and search for higher knowledge. ... Such teachings are unsafe rafts for crossing the ocean of ignorance.  Doomed to shipwreck are those who try to cross the ocean of ignorance on these poor rafts. Ignorant of their own ignorance, yet wise in their own esteem, these deluded people proud of their vain learning go round and round like the blind led by the blind.

The Soul, the innermost Self is verily Brahman (God in truth), being equanimous, quiescent, and by nature absolute Existence, Knowledge, and Awareness.  The Soul is not the ‘I’ which is non-existence itself.  The realization of this truth is called Self- Knowledge by the Sages of truth.

There is nothing that exists prior to consciousness. The ‘I’ cease to exist without consciousness. The Soul, which is present in the form of consciousness, is the ultimate truth or Brahman or God in truth. : ~ Santthosh Kumaar
