Kena Upanishad 2-5 . If you do not realize Brahman (God in truth) in one life, you are a great loser.+

Kena Upanishad 2-5 mentions that  Brahman (God)  can be realized in one life. If you do not realize in one life, you are a great loser.

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.

In ignorance there is duality. In wisdom, there is the only nonduality. The Soul the innermost self is one without the second. The Soul is present in the form of consciousness (spirit).  

It is the same consciousness (Soul) manifests as the whole universe. Consciousness itself is the ultimate truth or Brahman or God in truth.  Consciousness is the ultimate cause of the universe and it itself is uncaused.  The seeker of truth must convince himself of this truth by Soulcentric reasoning.

A Gnani wears no signs it means he does not identify himself as Guru or teacher or Swami. 

Sage Sankara: On Gnani: "The knower of Brahman wears no signs. Gives up the insignia of a monk's life…his signs are not manifest, nor his behavior." 

When the knower of Brahman (Gnani) wears no signs it means he does not identify himself as Guru or yogi or teacher or Swami. 

If someone has acquired Self-knowledge and shares his acquired knowledge with others, they cannot say that there is nothing for them to do. Everyone has to discover a fresh for himself by verifying all the facts. Each one has to grasp assimilate and realize it until he gets a firm conviction of the ultimate truth or Brahman.

The mind appears due to ignorance. Without ignorance, the mind (I) ceases to exist.  Thus, the mind is in the form of the universe and appears as a waking or dream.  The waking or dream is the state of duality. Thus, the seeker has to hold wherever there is duality there is ignorance.  

If the duality is considered as reality then the experience of birth, life, death, and the world is considered as a reality.  If the experience of birth, life, death, and the world is considered as reality then the form, time, and space become a reality. 

If form, time, and space become a reality as reality then there is diversity in unity.  To bring back the unity in diversity, one has to put the ego in reverse gear until it reaches the ultimate end or source from where the mind rises and subsides.      

Remember:~

The Seeker has to grow from the inside out by Soulcentric reasoning. None can teach him none can make him reach the ultimate end of understanding. There is no other guru, but the formless Soul or the consciousness, which is the Self.

If anyone is sharing Self- knowledge or Brahma Gnana or Atma Gnana they are doing a great help to humanity. I respect everyone who is sharing self-knowledge or Brahma Gnana or Atma Gnana.

There is no need to tell anyone.   The pursuit of truth is the pursuit of verification not the pursuit of an argument.  Self-knowledge or Brahma Gnana or Atma Gnana does not belong to any Guru or yogi because it is the universal property. 

Only those who have directly known truly realized the ultimate Truth and can have the perseverance and passion to share it.

From the  Nondualistic perspective, there is neither illusion nor delusion. The form, time, and space are part of the duality, which is merely an illusion. 

There is no such delusion in the realm of the  Nondualistic reality because form, time, and space are one in essence. That essence is the Soul which is present in the form of consciousness. Consciousness is the ultimate truth or Brahman because there is no second thing that exists other than consciousness.:~Santthosh Kumaar
