Can you explain the philosophical concept of non-duality and the transcendence of the senses as detailed in the latter part of Chapter 35?

Chapter 35 delves into the advanced philosophical state of non-duality experienced by a devotee. It describes how, for a true devotee, the focus on Sai Baba as the "ocean of mercy" causes the triad of the seer, the seen, and the act of seeing to vanish, completely erasing the sense of duality. This transcendence extends to all senses. The text explains that when a word is heard, Sai's form immediately manifests, and the triad of the hearer, the heard, and the act of hearing shatters. This illustrates a state of complete absorption where the devotee perceives only Sai in every aspect of existence.
