People who think they are born in this world and the world that existed prior to them have not gone into a deeper self-search.+

Till one thinks, he is an individual separate from the world he will not be able to assimilate  Self-knowledge or Brahma Gnana or Atma Gnana because he feels he is the doer/Author.  The sense of doership is within the waking experience which is merely an illusion. 

People who think they are born in this world and the world that existed prior to them have not gone into a deeper self-search.

People base themselves on the physical entity, stick to their intellectualism, and accept their accumulated knowledge as truth. 

People will not accept anything as truth other than their understanding on the base of ‘I’ which is the false base. 

People remain in confusion and try to argue on a physical base such arguments have no end because the truth is based on the formless and false is based on the form (ego or waking entity). 

Thus, whatever is seen known, believed, and experienced on the false base has to be a falsehood. 

The experience of birth, life, death, and the world which is based on the physical entity is part and parcel of the illusion.

Intellectuality is limited to physicality. Thus, the ego cannot cross the threshold of duality and they are stuck to finding the truth through sex, virtues, love, good deeds, and compassion which are the attributes of the false self within the false experience.

Until one gets convinced that the ‘I’ is not the Self, he will remain in ignorance of the formless Soul the Self. 

If the Self is formless, then the experience of birth, life, death, and the world is bound to be an illusion. 

It is necessary to know and realize that the Self is not the form, but it is formless before indulging in the inner (mental) journey.

Inquiry is not the set of questions but clearing all the doubts and confusion through deeper reasoning on his own. 

There is no scope for arguments in pursuit of truth because it is a personal journey that starts within the illusion (waking) and ends in realizing the truth. 

Thus, the arguments based on the false self will not lead one towards the non-dualistic goal. 

The seeker of truth has to share the assimilation of knowledge and help and inspire fellow seekers and divert their attention from outer to inwardness.:~ Santthosh Kumaar
