A person perceives the world within the mind.

 A person perceives the world within the mind.  Absent of mind is absent of waking or dream. Thus waking or dream is mind.

One thinks he is an individual separate from the world within the mind. He is unaware of the fact that the mind is not within his brain, but he and his experience of the world are within the mind.  Thus, he thinks he is born in this world and world existed prior to him. Thus this conviction makes him believe the birth, life and death as reality.  Until this conviction is thee he will   views and judges the worldview on the physical base, which is the cause of ignorance of the fact that, the true self is the soul.

This ignorance of the true self is the main hurdle in pursuit of truth. Therefore, it is very much necessary to rectify the seeking base from physical (form) to spirit (formless) before proceeding further in pursuit of truth.

If the seeking base is not rectified it will lead one towards hallucination. When the mind itself is myth then the man and his experience of the world is bound to be myth. Therefore perfect understanding of the mind will help one to unfold the mystery of the mind.  It is impossible to unfold the truth on the base of false self within the false experience, because the truth is prior to the appearance of the falsehood.  And falsehood creates ignorance.

Seeker has to burn down the ignorance by rectifying the base of reasoning by realizing the fact that self is not physical but it is the formless consciousness.

THE ‘I’ OR ‘I AM’ IS CAUSE OF THE IN IGNORANCE. Thus one has to get rid of the ignorance by overcoming the intoxication of ‘I’ or I AM which intoxication stuff in pursuit of truth is.

That is why Sage  Sri, Sankara says in( VC) :-

61. For one who has been bitten by the serpent of Ignorance, the only remedy is the knowledge of Brahman. Of what avail are the Vedas and (other) Scriptures, Mantras (sacred formulae) and medicines to such a one?

62. A disease does not leave off if one simply utter the name of the medicine, without taking it; (similarly) without direct realization one cannot be liberated by the mere utterance of the word Brahman.

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.

64. Without killing one’s enemies, and possessing oneself of the splendor of the entire surrounding region, one cannot claim to be an emperor by merely saying, ‘I am an emperor’.

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.
 

People who are yearning for spiritual truth will not find it through intellectual speculation and assumption. Intellectual truth is individual truth. Love implies duality and love is individual feelings within the falsehood. Love is necessary and valuable in the stated of ignorance but it is not the means to acquire wisdom.  Love is religious tool to lead life in practical world.  And Religious truth is individual truth and it is not universal truth because the religion is based on individuality.
