How does Chapter 12 explain Sai's role in helping devotees overcome duality, and who benefits from this teaching?

In its opening verses, Chapter 12 describes Shri Sai as the 'embodiment of Truth, Consciousness, and Bliss' who has the power to still the waves of worldly existence. The chapter states that through the 'knowledge of non-duality,' he can remove the 'obsession with duality' even from those who are dull-witted. This teaching is not just for the intellectually inclined; in fact, the chapter emphasizes that saints like Sai make no distinction between people. It explicitly states that to saints, the virtuous and the wicked are equal, and they treat both with the same compassionate regard. Therefore, Sai's role is to extend this grace to all, helping any surrendered soul move beyond divisive concepts towards a state of unity.
