Peoples approach is more practical, and they stuck with the reality of the world, they take it as real. That is why all the confusion.

'Ain al Haque'--  spiritually it means 'Self is the Truth'  but it is physically  interpreted as I AM the Truth. Thus it is not different from 'AUM' of Vedanta which means 'Self" ,aligning the self with ultimate reality or Brahman. one has to learn to judge the worldview on the standpoint of the formless soul, the innermost self, in order to unfold the mystery of the mind or universe.  

The problem arises when the person views and judges the truth on the base of the ego or waking entity and looks upon the world as reality. such person become egocentric. 

  

The world is both real and unreal. It is real because it is a manifestation of consciousness, but is unreal, in the sense, that it is not absolute and eternal like consciousness itself.

Peoples approach is more practical, and they stuck with the reality of the world, they take it as real. That is why all the confusion.

That is why Sri, Sankara says :-   

(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.

When non-dual wisdom dawns, then the universe (duality) becomes a mere mirage created out of consciousness.  The duality is present only when the universe is present.  If the universe is a mere mirage than the duality also is mere mirage.   Thus all the illusory bonds of duality brakes and the ‘self’ is liberated from the clutches of duality which was experienced as reality. Same way as the dream becomes unreal when waking takes place the duality becomes unreal when wisdom dawns.

Many think that it is worthwhile to acquire the miraculous powers through the practice of yoga and mysticism which in turn help him to create whatever they want wants in practical life.

When the waking experience itself is an illusion then what is the use of miracles performed within the illusory experience. Whatever is based and performed on the base of  waking entity or ego is bound to be part of the falsehood. Hence miracles are part and parcel of illusion.

Those who are wedded to philosophical and scriptural knowledge will permanently remain in illusion believing their philosophical knowledge as real wealth.

Until and unless they make sure 'I' is not self and the world is unreal through deeper self-search they are bound to believe their intellectual accumulated knowledge as wisdom. 

The wisdom is knowledge of the reality which is beyond the form, time and space.

Philosophical and scriptural knowledge which are based on ego as self are not useful in pursuit of truth
