Self-Awareness must be got in the midst of Waking experience

Self-Awareness must be got in the midst of  Waking experience. The analogy of deep sleep is to indicate that deep sleep is the last gate to be passed before reaching the soul, which is the innermost self.

Deep sleep is definitely not the condition of the Awakened Mind or Gnani. Otherwise it would keep returning to deep sleep in order to recover its wisdom. Deep sleep and Samadhi gives idea of non-dual experience alone, whilst waking experience gives the idea of non-dual plus duality. Hence, the soul is ever-present in the midst of the Waking life as its witness and substance. 

 The Seeker by knowing that the Deep sleep gives non-dual experience is not enough. It must be known and realized in the Waking experience. That is the Seeker has to discover it in the midst of the waking experience by deeper self-search reveals:- into the nature of the mind and trace back the formless witness of the three states. Then only he will be able to acquire Self-Knowledge or Brahma Gnana or Atma Gnana
