Can you explain the philosophical concept of non-duality (Advaita) and the awakening of 'Soham' as presented in Chapter 6 of the Sai Satcharitra?

Chapter 6 delves into the profound spiritual transformations facilitated by the Sadguru, including the realization of non-duality, or Advaita. The text describes how Sai Baba awakens the sense of 'I am He' (Soham) within a devotee, revealing their innate bliss. This process involves dissolving the sense of 'me and mine'—the ego-centric identity that creates a feeling of separation from the divine. By doing so, as this chapter outlines, the Sadguru helps manifest the harmony of non-duality, where the distinction between the individual self and the ultimate reality dissolves. This experience is marked by supreme bliss, where looking at the Guru's form can choke the throat with emotion and bring tears of joy, indicating a deep, internal shift toward unity.
