How does Chapter 12 explain Sai Baba's role in teaching non-duality and practicing equality?

Chapter 12 of the Sai Satcharitra portrays Sai Baba as an embodiment of Truth, Consciousness, and Bliss who helps remove the obsession with duality, even for the dull-witted, through the knowledge of non-duality. This principle is reflected in His actions and nature. The chapter explicitly states that He has no feeling of friend or foe and that to Him, the pauper and the king are the same. Furthermore, it explains that for saints, the virtuous and the wicked are equal, and their minds do not differentiate between who is great or small. This demonstrates a profound commitment to equality and the practical application of non-dual philosophy.
