How does Chapter 12 explain Sai Baba's role in helping people understand non-duality?

Chapter 12 presents Sai Baba as a guide who helps people transcend a dualistic worldview. He is hailed as the "embodiment of Truth, Consciousness, and Bliss" who, through the "knowledge of non-duality," removes the "obsession with duality even from the dull-witted." This teaching is not just theoretical. The chapter illustrates this principle by describing Sai's own conduct: He maintains an "enmity-free equality everywhere" and perceives no difference between a pauper and a king. By embodying this non-dual state, Sai Baba provides a living example, helping devotees move beyond the illusion of separation and experience a more unified reality, as explained in Chapter 12.
