The purpose quest for truth is to first find out what is the untruth to realize the truth and discard the untruth.+

The Soul, the Self is verily Brahman (God), being equanimous, quiescent, and by nature absolute Existence, Knowledge, and Awareness.  The Soul is not the ‘I’ which is non-existence itself.  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.

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

The ‘I’ hides Soul, the Self, Soul is God in truth.

Bhagavad Gita: ~ “You must first see the ‘I’ as illusory before you see others as illusory. ~ CH.2 v.16

First, you must make sure the ‘I’ itself is illusory because the ‘I’ is not permanent. The seeker has to find for himself the truth of the true existence and to come to a fuller and deeper understanding and realization of the truth, which is hidden by the illusory form, time, and space.

The purpose quest for truth is to first find out what is the untruth to realize the truth and discard the untruth.  

As an individual, you are unaware of the Self, which is hidden by the dualistic illusion. The dualistic illusion 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 Soul, the Self is unaware of itself in the dualistic illusion or Maya.  

The individual realizes that he is Brahman on the Awareness of being Brahman.  So it is Brahman, who is under ignorance.  It is He who receives the instruction in this process.  Because the instruction is being received by Him, it is a teaching.  Thus the instruction becomes one with what is taught and through that it becomes one with the Supreme Brahman.  Hence you cannot state that the instruction lacks the ‘value as a teaching’ in it.  This whole scenario is applicable only in the case of ignorant people.  In the case of enlightened people like us, as you said, instruction cannot have the ‘value as teaching.’

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

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 the 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.

Gnani and Illusion.

A King who was greatly incensed at the wisdom taught by Gnani that everything here below is an illusion. He wanted to teach the exponent of this doctrine a lesson. So he invited the then Gnani to his palace. That Gnani went there and stoutly maintained that everything in this world is an illusion.

The king had arranged to let loose a hungry lion against Gnani. The beast rushed at Gnani who took to a precipitate flight to save himself.

'Oh, Venerable Sir,' shouted the king, 'why do you run so fast seeing that the lion is only an illusion?'

'Oh, king,' said Gnani in the course of his flight, 'my running too is an illusion. Everything in this world is an illusion.’

Similarly, whatever takes place in this world, in which you exist, is an illusion. The Avatar based on mythology is a religious fable. God is not an individual. Avatar belongs to the domain of form, time, and space whereas God is formless, timeless, and spaceless existence.

The world in which you exist is created out of God and God is present in the form of consciousness. Thus everything is created out of God, thus all animate and inanimate things of the world are nothing but God. It is foolish to say only some human being as an Avatar the whole illusory creation is Avatar of God. Only those who have realized the body is not the Self and the Self as the innermost 'Self', like Meher Baba, can say of the Avatar because his vision of the world is Soulcentric.

Remember:~

In mystical realization, they call Self- Realized person as Avatar.  In spiritualistic realization, they call the Self-realized person as Gnani. A Gnani is the one, who is fully aware of the fact that  the Self is not the form but Self is formless consciousness and  he considers his body and his experience of the world as an illusion created out of  the Soul or the consciousness

Righteousness, peace, and love to divinity are necessary within the dualistic illusion. Righteousness, peace, and love for divinity are created out of consciousness. Without consciousness, there is no Righteousness, no peace, and no love. Realizing the consciousness as the ultimate truth is truth realization.

Righteousness, peace, and love to divinity are necessary for practical life within the practical world, but they are no qualifications for truth realization.

A Gnani vision of the world, in which he exists, is, beyond time and space, embracing the Soul, ultimate reality. The universe in which you exist is within the Soul, the Self.

Gnani observes the reality is hidden by the dualistic illusion (world) as it is in the midst of the dualistic illusion.

Self- Knowledge is only is true knowledge not the absence of duality. Self -Knowledge cannot destroy the world but it eliminates ignorance and exposes the unreal nature of the mind or universe.

A Gnani is the one who has realized the universe in which he exists is nothing but consciousness. Self-awareness is unique. It cannot be experienced because it is prior to any experience. It is possible only by the realization of the knowledge of the Infinite."

A Gnani sees only unity in diversity, just like a goldsmith estimating the gold in various items of jewelry sees only gold. When one identifies the Self with the form then only the form, time, and space are present. But when one transcends form, time, and space the duality never remains as reality.

The world in which you exist is not separate from the Soul, which is present in the form of consciousness because the world in which you exist is an illusion created out of consciousness. : ~ Santthosh Kumaar
