What is the philosophical basis for unity in Sai's teachings that can help a community overcome division?

The philosophical basis for unity, as detailed in Chapter 37, is the understanding of non-duality. The text states that the same divine principle, Parabrahman, pervades everything from the creator down to the smallest blade of grass. The delusion of being separate from this Brahman is the root of ignorance and the cycle of worldly existence. A community can overcome division by internalizing this truth: that we are all part of the same cosmic Self-form. Believing 'Parabrahman is different from me' is what subjects one to the cycle of death and rebirth, whereas seeing the one in all fosters unity.
