Ish Upanishad declares:~ Those people who have neglected the attainment of Self-knowledge and have thus committed suicide.+

The Advaitic Truth is simple, but it is very difficult to grasp because people are stuck up with their accumulated knowledge, which blocks their realization.

People don’t realize the Gnana is already there but they have buried it under their accumulated knowledge and they don't want to check that is why they miss it. They refuse to accept anything other than their mental Garbage.

All accumulated knowledge from different Gurus and different sources and different ideologies and different philosophies have buried the truth under mental Garbage. People are stuck with their religion and religious doctrine and Gurus and their Gurus teachings and refuse to accept anything as the truth other than their accepted truth.

That is why Sage Sankara says:~ A buried treasure is not uncovered by merely uttering the words: “Come forth.” You must follow the right directions, dig, remove the stones and earth from above it, and then make it, your own. In the same way, the pure truth of the Atman, which is buried under Maya and the effects of Maya, can be reached by meditation, contemplation, and other spiritual disciplines but never by subtle arguments.

Sage Sankara goes on to say: ~A sickness of not cured by saying the word “medicine.” You must take the medicine. Liberation does not come by merely saying the word “Brahman.” Brahman must be realized. Until you allow this apparent universe to dissolve from your consciousness until you have realized Brahman, how can you find liberation just by saying the word Brahman? The result is merely noise. Until a man has destroyed his enemies and taken possession of the splendor and wealth of the kingdom, he cannot become a king by simply saying “I am a king.”

That is why Sage Sankara:~ VC- v6~ Let erudite scholars quote all the scripture, let Gods be invoked through sacrifices, let elaborate rituals be performed, let personal Gods be propitiated---yet, without the realization of one‘s identity With the Self, there shall be no liberation for the individual, not even in the lifetimes of a hundred Brahmas put together.

Fortunate are those who do not lose themselves in the labyrinths of accumulated knowledge. They are conceptual divisions invented by the Gurus in the past by their excessive analysis. All these concepts create so much of doubts and confusion. 

Adhyasa Bhashya of Sage Sankara:~ (11.2) In short, a person who engages in rituals with the notion “I am an agent, doer, thinker”, according to Sage Sankara, is ignorant, as his behavior implies a distinct, separate doer/agent/knower; and an object that is to be done/achieved/known. That duality is avidya, an error that can be removed by Vidya.  

Adhyasa Bhashya of Sage Sankara: ~ (12) Sage Sankara affirming his belief in one eternal unchanging reality (Brahman) and the illusion of plurality, drives home the point that Upanishads deal not with rituals but with the knowledge of the Absolute (Brahma Vidya) and the Upanishads give us an insight into the essential nature of the Self which is identical with the Absolute, the Brahman. 

Sage Sankara: ~ Atman, the innermost self is verily Brahman (God), being equanimous, quiescent, and by nature absolute Existence, Knowledge, and Bliss. Atman is not the body that is non-existence itself. This is called true Knowledge by the wise. 

Sage Sankara says:~  Yoga is not the means of liberation. (p-132`133  commentary on Brihadaranyakopanishad).

Brihad Upanishad:~ Even yoga cannot give perfect concentration and the only way to gain it is through philosophical realization. This confirms the Manduka Upanishads' statement that yoga can no more succeed than the ocean can be emptied with a blade of grass. (p~133~Ist par) 

In Sutra Bashya and Manduka:~  Samadhi and sleep are identical. 

Brihad Upanishad does not advocate Samadhi. People are going down, down, and down.

The mantra-yoga consists of repeating the name of God, or even the AUM; thousands of times yield nothing. It can appeal only to the ignorant, to those who cannot think deeper. It is a mere religious fable. The real exercise is to think of the meaning of the name or the AUM and then only do you get something.

Mantras can do nothing. If they really had any power why did not Krishna use one to stop the Mahabharata war? All the magical power of mantras are a religious fable because religion is based on the false self(waking or ego) and false experience(waking or the world)  Visions and Samadhi are illusions from the standpoint of the Soul, the  Self.

That is why Sage Sankara:~ VC-  63. Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.

Ish Upanishad declares ~ Those people who have neglected the attainment of Self-knowledge and have thus committed suicide.

Those people who have neglected the attainment of Self-knowledge and have thus committed suicide, as it were, are doomed to enter those worlds after death.

This is a condemnation of people who do not try to attain Self-knowledge.  In a real sense, they are committing suicide, for what can be worse than being a slave to sense enjoyment, completely oblivious of the real purpose of life, which is to be one’s, own master?

Mundaka Upanishad:~  The study of the Vedas, linguistics, Rituals, astronomy, and all the arts Can be called lower knowledge. The higher Is that which leads to Self-realization. The eye cannot see it; the mind cannot grasp it. The deathless Self has neither caste nor race, Neither eyes nor ears nor hands nor feet. Sages say this Self is infinite in the great And in the small, everlasting and changeless, The source of life.

Manduka Upanishads:~  Those that want ultimate truth Brahman will not practice control of the mind. ( p.231)

In the pursuit of truth discussion of the unimportant subject matter is a great hindrance. Personal attacks and perverted arguments are a hindrance to realizing the truth beyond form, time, and space.

The path of truth is the path of verification. Nothing has to be accepted as truth without verification. Agreeing to disagree causes unnecessary friction, everyone has a point of view and everyone must respect others' views wisdom just to maintain harmony irregardless of whether the point made was acceptable or not.

There are millions in search of truth, but one in million will be able to grasp it.  I am just posting what revels from the inner core. I just share with like-minded fellow seekers.   I am just highlighting the obstacle in the pursuit of truth.  Self-Knowledge or Brahma Gnana or Atma Gnana is not based on any teaching or teacher. The pursuit of truth is the pursuit of verification not the pursuit of an argument.   Intellectual discussion is a great hindrance in the pursuit of truth.

Sharing is giving info for the sake of goodness. As with all things, achieving a balance of peaceful communications is established with respect, humility, understanding, and patience. Balancing an achievement is harder.:~Santthosh Kumaar
