A person who realized the ultimate truth or Brahman will throw off his religious robe and all religious identity +

All the Gurus and yogis are holy people who belong to religion and yoga, not spirituality. 

Advaitic Gnana has nothing to do with the Gurus, yogis, pundits, and priests. Advaitic Gnana is not for those who believe in religion, or religious Gods and are stuck up with religious rituals and ceremonies. 

Religious believers are not truth-seekers because they have accepted their religious beliefs as the ultimate truth.

Advaitic Gnana is knowledge of the Spirit, the God in truth. God in truth is Advaita, the one without the Second.

A person who realizes the ultimate truth or Brahman will throw off his religious robe and all religious identity and live like a commoner.

A Gnani never identifies himself as a Gnani nor does he identify himself as superior to others. He only shares his knowledge with fellow seekers.

A Gnani never identifies himself as a Guru or a Yogi or someone disciple. The one who accepts himself as a Guru or someone’s disciple is not a Gnani.

Ashtavakra Samhita: ~ "The man of knowledge (Gnani), though living like an ordinary man, is contrary to him, and only those like him understand his state.

A Gnani can point at the sky, but the seeing of the star is the seeker's own work.

If you are trying to become a Guru or Monk then you are unfit to acquire Self -knowledge. Someone posing as a Gnani, because he is some Gurus’ direct disciple cannot be a Gnani. Those who pose themselves as Gnanis are not Gnanis. A Gnani never poses himself as a Guru, a swami, a Sadhu or a yogi, or some Guru’s disciple.

Different Gurus and teachers are pointing out the understanding of the Advaitic truth from different standpoints. All such understanding of Advaita is on the dualistic perspective accumulated from here and there.

Sage Sankara: ~ "Though I wear these robes of a Sanyasin, it is only for the sake of bread." 

Sage Sankara: ~ A Gnani "bears no outward mark of a holy man" (Stanza 539).

Thus, it proves that religious Gurus and yogis are not Gnanis because they identified themselves as holy people.

A Gnani never claims himself as a Gnani, he guides the seekers, not posing himself as a Guru, and he does not force his wisdom on others.

Advaita is not a theory or philosophy. Advaita is the nature of the Soul the Self. There is no need for any theory or philosophy or scriptures to acquire Self -knowledge of Brahma Gnana or Athma Gnana. Only a perfect understanding of ‘what is what’ is needed.

Sage Sankara:~ Actual realization takes you beyond books. At a certain stage, books become a botheration.

Bhagavan Buddha: ~ Do not believe in anything merely on the authority of your teachers and elders.

You need not become a Guru or a monk to acquire Self-knowledge or Brahma Gnana or Atma Gnana.

You have not to renounce the world or to leave anything ~ your wife, children, job, responsibilities. You do not have to renounce anything! The only thing you have to realize is the truth, which is hidden by the illusory form, time, and space by realizing the form, time, and space are the product of ignorance.

When the ignorance vanishes, then the unreality of the form, time, and space, is exposed.

Upanishads say ~ "He who thinks he knows, does not know." This means that to know anything implies a second, an object of knowledge, hence duality, i.e. no Gnana. 

Tripura Rahasya: ~ Second-hand knowledge of the  Self’ gathered from books or Gurus can never emancipate a man until its truth is rightly investigated and applied; only direct realization will do that. Realize yourself, turning the mind inward. (18: 89) : ~ Santthosh Kumaar
