The Seeker after the truth should take to soul centric reasoning and discriminate between dual and non-dual experiences to realize what the truth is and what is untruth.

The real Moksha or freedom is   to realize the fact that ‘I’ consciousness is mere physical awareness. Physical awareness is not self-awareness. The self –awareness is when the formless soul or consciousness remains aware of its own non-dual   true nature. – FORMLESS PATH 

This universe is common to all of us, therefore one must include the universe his investigation in order to realize the ultimate truth or Brahman.   It is only after one has inquired into the nature of the objective universe, that he should inquire into who is the knower. If, however one   inquiries into the knower before the inquiry into the universe, then it is mere mysticism.  One must have the perfect understanding of what is what. 

v  “What is the universe?

v  What is this ‘I’?

That is why Sri, Sankara indicated in (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.

65. As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent Truth of the self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman, followed by reflection, meditation and so forth, but not through perverted arguments.

The Seeker after the truth should take to soul centric reasoning and discriminate between dual and non-dual experiences to realize what the truth is and what is untruth. 

The seeker who has an intense urge in knowing the truth and sharp in grasping, skills in understanding and assimilating without the scriptures, the one who has got these characteristics is the fit recipient of the self- knowledge.

People, who have not become firm in their power of reason, quote someone else as authority to support their reasoning because they have not got fullest confidence in their own powers. 

When one is certain, he does not need any authority to support or confirm himself. There is no need for it. To appeal to others views, indicates his own reasoning is incomplete. Thus seeker has to do his own homework independently. 

Gnanis quote the verified citation of scriptures or sages of the past just to inspire the seekers who hold scriptures are the ultimate authority to show the scriptures or sages are saying the same thing. 

The seeker must not tell a lie is the first requirement in the pursuit of truth.” What he like for practical life it is not concerned with the ultimate truth or Brahman. The Seeker has to keep his intuitions and instincts at a distance and he has to stick to known fact. To inquire, analyze and reason means to go to the very end of things. 

Sharpness to grasp the truth is necessary in pursuit of truth. By merely hearing the truth mentioned they will grasp it. 

The seeker has to analyze the three states; and he has to think consistently on it. Exercise his thinking faculty and inquire continually; discrimination is essential; this practice is the only way to understand, assimilate and realize the non-dual truth.
