ಉಪನಿಷದ್ಗಳು ಹೇಳುವ ಹಾಗೆ :

The famous utterance of Upanishad that Brahman cannot be attained by duality is in RV (5.12.2). The idea that Brahman cannot be attained by mere action or effort is in RV (8.70.3) and (5.48.5); Brahman cannot be approached by thought (RV.1.170.1 or Kena U., 1.3). [RV=RIG VEDA]

Ashtavakra says: - "This is your bondage, that you practice Samadhi meditation.”

When one puts aside the imagination and has the thinker-- what does he get with thinking—he can get only a thoughts. Meditation is only an effort; it is imagination, an idea; the soul/consciousness   remaining the same with or without ideas. 

Mundaka Upanishad says:  The rituals and the sacrifices described in the Vedas deal with lower knowledge. The sages ignored these rituals and went in search of higher knowledge. ... Such rituals are unsafe rafts for crossing The sea of samsara, of birth and death. Doomed to shipwreck are those who try to cross The sea of samsara on these poor rafts. Ignorant of their own ignorance, yet wise In their own esteem, these deluded men Proud of their vain learning go round and round Like the blind led by the blind.

Isa Upanishads indicates that: By worshiping gods and goddesses and going to the world of gods after death is of no use.  The time one spends in ritualistic practices is wasted; one can spend same time moving forward towards Self-knowledge, which is the main goal. One cannot reach the non-dual destination by glorifying god and goddesses and by doing that, one goes deeper and deeper into darkness. It surely indicates the fact that, the seeker of truth has to drop the worshiping god and goddess in order to get self-knowledge.

  

 This Atman cannot be attained by the study of the Vedas, or by intelligence, or by much hearing of sacred books. It is attained by him alone whom It chooses. To such a one Ataman reveals Its own form. [Katha Upanishad Ch-II -23-P-20]

This Atman cannot be attained through study of the Vedas, nor through intelligence, nor through much learning. He who chooses Atman—by him alone is Atman attained. It is Atman that reveals to the seeker Its true nature. [    3 –page-70 Mundaka Upanishad  Upanishads by Nikilanada]

Katha Upanishad says:

Fools dwelling in darkness, but thinking themselves wise and erudite, go round and round, by various tortuous paths, like the blind led by the blind. [Ch II-5 P-14]

    

Raman Mahrshi further explains [in page 111/112- practical guide to know your self]:-

Q: D: Is it not necessary to study the Vedas or at least Prastnatraya[Bagvad gita.Dasoponishad and Brahma Sutra all with commentaries] to ensure firm reazation?

A: Bhagvan: - No. Do you need all that to see yourself? All that is intellectual wealth, useful in explain doubts and difficulties if others rise them if you yourself encounter them in course of thinking. But to attain realization, all that is not necessary. You want fresh water to drink, but you do not require all the water of the river Ganges to quench your quest.

  

They alone in this world are endowed with the highest wisdom who are firm in their conviction of the sameness and birthlessness of Atman. The ordinary man does not understand their way. [Chapter IV — Alatasanti Prakarana 95-P-188 in Upanishads by Nikilanada]

   

Nisagadutta said:  Millions are in search of the ultimate truth, and only one in million will be able to grasp and realize it. 

Katha Upanishad says:

[Upanishads Nikhilananda]

Fools dwelling in darkness, but thinking themselves wise and erudite, go round and round, by various tortuous paths, like the blind led by the blind. [Ch II-5 P-14]

    
By focusing more attention on Ataman by talking, writing, discussing only of Ataman, the conviction grows and becomes firmer and the duality will fade away as reality. Ataman/sprit which is one’s   true identity will prevail as birth-less and deathless, eternal substance and witness of the mirage called duality  or mind.
