In mystical realization, they call a God-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 the Self is formless consciousness,  and he considers his body and his experience of the world as a mirage created out of the Soul or the consciousness.

The Soul is the Self. The Soul is present in the form of the Spirit. The Spirit is the ultimate truth or Brahman or God in truth. 

Religious Gods are not God in truth.  Gnani does not say God is not there, God is, but not as one imagines God. God is above all imagination. 

The existence is Brahman. The existence without the ‘I’ is the ultimate truth or Brahman. The existence can remain with or without the ‘I’.  

God exists as the ultimate truth. Hence, in the path of wisdom do not use the word, God. It will be misunderstood.  

Thus, Brahman, which means the ultimate truth, is the right word. Just for the communication to indicate the ultimate truth, the word God is used to indicate God in truth, which is Atman, the Brahman.

BRAHMAN -The English use of the word real as applied to the material world, whereas Indian Sages of truth use it as applied to unseen Brahman. Hence many errors have arisen in translations from the Sanskrit.

BRAHMAN- The word Brahman or Sat has no proper equivalent in English. The nearest is ultimate reality or ultimate truth. The West, however, applies reality to individual objects or to the multiplicity of them all: whereas Advaitins apply it to the non-duality. Brahman is called "That" because it is something not known yet by the seeker.  

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 a Guru or a Yogi or teacher or Swami.

Manduka Upanishads: - It is very difficult to find out who is a Gnani because he bears no external mark. Neither nudity nor the yellow robe has anything to do with him.

A scholar is proud that he has accumulated so much knowledge; Gnani is humble that he knows no more. 

Sage Sri, Sankara's commentary to Brahma Sutras (Chap.3.4.50) shows that the Gnani "should pass through life", not run away from life, and should take a middle course between seeking worldly honor and worldly abasement. 

Yoga Vasistha: The greatest Gnani: “His state is indescribable yet he will move in the world like anybody else," ..." Though acting after every feeling such as love, hate, fear and the like, he who stands unaffected within is said to be real jivanmukta." Sankara's commentary.

Yoga Vasistha says of the Gnani: "He is a great worker." It also so says, that he keeps his body healthy, and does not starve it.

Remember:~ 

A Gnani cannot have the idea of renouncing the world or giving up something of the practical world, because that would connote the idea of duality.  

Duality is merely an illusion from the ultimate standpoint. Knowing no second thing at all there remains nothing to be given up.

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 a reality.

A Gnani will never force anyone to accept the path of wisdom. He will constantly bring the seeker back to the fact of his inherent perfection and encourage him to seek the truth, which is beyond form, time, and space. 

A Gnani knows you need nothing, not even him, and is never tired of reminding you.  A Gnani continuously shares Self-knowledge or Bramha Gnana or Atma Gnana with like-minded fellow seekers. 

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 or God in truth.

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 a state of duality. Thus seeker has to hold wherever there is duality there is ignorance.

If duality is considered as reality then the experience of birth, life, death, and the world are considered as reality. 

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

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

Remember:~ 

Sage  Sankara says the transparent Truth of the Self, which is hidden by the illusion, is to be attained through the instructions of a knower of Brahman, (Gnani).

First, know ‘what is the truth’ and ‘what is untruth’ for sure. Without realizing what untruth truth is, it is difficult to know what truth is.

When the sky, clouds, and the world in which you exist are made of single clay then there is no second thing that exists, other than that clay. That clay is the Soul, which is formless, timeless, and spaceless existence.

Reality is hidden by the unreality. The world in which we exist hides the truth.  Whatever belongs to you is unreal. The words and thoughts belong to you, not to the Soul, which is the ‘Self.'

Whatever has a name and form and attributes and whatever belongs to form, time and space is an illusion. The illusion hides the Spirit, which is God.  The illusion and Spirit are one in essence.  Spirit, the God alone is real and eternal.  : ~ Santthosh Kumaar
