Based on the teachings in Chapter 12, how does Sai Baba remove the 'obsession with duality'?

Chapter 12 of the Sai Satcharitra teaches that Sai Baba, as an 'embodiment of Truth, Consciousness, and Bliss,' helps his followers overcome the 'obsession with duality.' He achieves this through the knowledge of non-duality. The text explains that to saints like Sai, 'the virtuous and the wicked are equal,' and they see no difference between a 'pauper and the king.' By embodying and demonstrating this 'enmity-free equality everywhere,' Sai Baba provides a living example of a consciousness that transcends dualistic judgments, thereby helping even the 'dull-witted' to move beyond the limiting perceptions of friend versus foe, good versus bad, and self versus other.
