How does Chapter 12 explain Sai Baba's role in helping people overcome the 'obsession with duality'?

In Chapter 12, Sai Baba is presented as a spiritual guide who helps devotees transcend duality. The text describes Him 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 is further illustrated by His own example of "enmity-free equality everywhere," where He makes no distinction between friends and foes or between a pauper and a king. By embodying this principle of non-duality and treating everyone as equal, Chapter 12 suggests Sai serves as a living example and a powerful force for helping his followers move beyond a dualistic worldview.
