When one becomes soul centric than only it is possible to decide ‘what is truth’ and ‘what is not truth’.

 All the doubts and confusion will remain until one  bases his self as the  ego, which is false self. Thus self realization is necessary  in order to become soul centric.  When one  becomes soul centric than only it is possible to decide  ‘what is truth’ and ‘what is not truth’.  

Accumulated egocentric knowledge is not yardstick in pursuit of truth because the truth  has to be ascertain by seeker himself by deeper self-search . Until one mentally rectifies his reasoning  base from form(waking entity  or ego) to formless(soul or consciousness) it is difficult for anyone to understand and assimilate the non-dual truth.

 It takes a long time to learn to view the worldview on the base of soul,which is the true self. Only deeper self search will lead one towards the inner reality. FP blogs are mere signpost for advanced fellow  seekers. No seeker of truth will accept anything as truth because it is said in FP blogs but he will verify them  personally and he will accept only  if it is un-contradictable truth. 

Studying of scriptures is not necessary

The Upanishads clearly indicate:-

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 Atman 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 Ataman attained. It is Atman that reveals to the seeker Its true nature. (3 –page-70 MundakaUpanishad (Upanishads by Nikilanada)

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

Q: D: Is it not necessary to study the Vedas or at least Prastnatraya(Bagvadgita.Dasoponishad and Brahma Sutra all with commentaries)to ensure firm realization?

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.

Raman Maharshi:- fortunate are the one who do not lose themselves in the labyrinths of philosophy. Bhagwan says: Take Vedanta, for instance: it speaks of 15 pranas the names and functions of it   which the student is asked to commit memory. Will it not be sufficient if he thought only one prana does the whole work of maintaining the body? Again the antakaran is said to think, to desire, to will, to reason etc. Why all these details? Has anyone seen antakarana, or all these pranas? Do they really exist? They are conceptual divisions invented by teachers of philosophy by their excessive analysis. Where do all these concepts end? Why should confusion created and then explained away? Fortunate is the man who does not lose himself in the labyrinths of philosophy, but goes straight to the source from which they all arise. (GURU RAMANA .By S.S Cohen -vii Danger of philosophy-Page -58-59)

The above passages further prove that: Self-Knowledge cannot be attained by study of the Vedas and intellectual understanding or by bookish knowledge.  Therefore there is no use of studying the Vedas and other scriptures in order to acquire the non-dual wisdom.  That is why Buddha rejected the scriptures, and even Sri, Sankara indicated that, the ultimate truth lies beyond religion, concept of god and scriptures.  

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 — AlatasantiPrakarana 95-P-188 in Upanishads by Nikilanada]

Therefore, there is no use of taking strain to understand assimilate the conceptual divisions invented by teachers of philosophy by their excessive analysis. There are more and more doubts and confusions, if one tries to understand and assimilate the ultimate truth through scriptures.
