By realizing the formless substance and witness are one in essence leads one to self-awareness.

Renunciation is getting rid of ignorance, which is cause of experiencing the illusion as reality by realizing the soul or consciousness is the innermost  self and cause of the illusion and it itself is uncaused.

The resting of the mind steadfastly on its true nature, which is consciousness after having mentally detached from three states by continually observing their unreal nature, one enters into nondual self-awareness.

Acceptance by firm judgment and conviction the un-contradictable truth derived from the deeper self-search as truth, by means of which the Reality is perceived.

The three states are mere illusion created of consciousness. Thus one becomes free from experiencing the illusion as reality, which is the cause of burden and bondage.

Verifying through inquiry into the truth of one’s true existence is devotion. The seeker of truth through deeper self-search by realizing the fact that, the self is neither the waking entity nor the dream entity but the self is the formless substance and witness of the three states. The formless substance and witness is consciousness, which is the inner most self. Mentally rectifying the reasoning base from form to formless is necessary in order to drop physical based intellectuality.  

Yearning for freedom from experiencing the illusion as reality by realizing the self is not the form but formless and self is not limited to the body but it pervades the whole universe as its formless substance and witness. Once one becomes aware of the unreal nature of mind, which is in the form of universe than he becomes aware of the fact that, the individual experience of the birth, life and death mere mirage created out of consciousness.  Constant reflecting on the formless substance and witness of the three states and by realizing the formless substance and witness are one in essence leads one to self-awareness.
