There is nothing to practice on the base of waking entity, because waking entity(ego) is not the self

There is nothing to practice on the base of waking entity, because waking entity(ego) is not the self. Perfect understanding and realization of what is what is most essential.  

Practice implies duality. Duality is illusion from ultimate standpoint. To know the innermost self, one has to become aware of  the existence of the formless witness of the three states.  Thus it is  mental journey. 

To be the innermost self, one has to stop imagining the self to be this or that.  Just being the waking entity   the Self-Knowledge or Brahma Gnana  or Atma Gnana will not   emerge. 

One has to find answers for: - What is that becomes waking? What is it that becomes dream? What is that becomes deep sleep.  As one goes in deeper self-search he becomes aware of the fact that the consciousness alone is the cause of the three states and it itself is uncaused. Until one thinks the self is limited to an individual and it is within the heart he will never be able to come out of physicality. The self is not an individual because it pervades in all the three states and it is formless substance and witness of the here states. 

  The individual experiences of birth, life, death and the world are nothing to do with the self because the self is birth -less and deathless.  The form, time and space are nothing to do with the self, because it is formless, timeless and space less existence.  Thus judging the truth on the bases of form, time and space is erroneous.  Thus ‘I’ or ‘I AM’, which is limited to physicality, will yield only half truth. 

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.

 By becoming more and more intellectual one becomes more and more intoxicated to individuality. The intellectuality is limited to duality.  In realm of truth the intellectuality is replaced by non-dual wisdom.  In self awareness  there is only  formless non dual existence. Therefore, there is   no individual. without the individual  there is no duality. There is no second thing exists, other than consciousness.  Everything is one, that is, unity in diversity. The curiosity, urge cannot be imposed on others.  it has to sprout within.
