Thus it is necessary to go beyond the WHO AM ‘I’ - inquiry to unfold the mystery of the form, time and space.

When the soul or consciousness, the innermost self, rises as mind (universe or waking or illusion) and subsides back its formless non-dual true nature then there is only Self-Awareness or Brahmic- Awareness or Atmic- Awareness. 

Deeper discrimination between dual (waking or dream) and non-dual (deep sleep) experiences leads the seeking mind in to self-awareness or Brahmic- Awareness or Atmic -awareness.  

In Self-Awareness, the body ego and the world are one in essence.  In self-awareness the form, time and space are one in essence. In self-awareness the three states are one in essence. Thus ‘I’ awareness is not Self-Awareness because ‘I’ is not the self. 

All the senses, thoughts and individual experiences and the world are present only in waking or dream. Waking or dream [duality] disappears as deep sleep (non-duality). Thus what becomes dual and non-dual experience is most impotent than inquiring ‘WHO AM I?’ - -inquiry, is limited only to waking entity or ego whereas the consciousness (soul) pervades in everything and everywhere in all the three states.  Thus it is necessary to go beyond the WHO AM ‘I’ - inquiry to unfold the mystery of the form, time and space.
