Can you explain the concept of non-duality and the dissolution of the 'triad' as described in the latter part of Chapter 35?

In its latter verses, Chapter 35 describes a profound mystical state of non-duality experienced in Sai Baba's presence. This goes beyond simple devotion and into advanced spiritual philosophy. The text explains that for the devotee, the "triad of the seen, the seer, and the seeing vanishes, erasing the place of duality." This means the separation between the observer (the devotee), the observed object (Sai Baba), and the act of observation itself dissolves into a single, unified experience. Chapter 35 extends this concept to all senses, stating that in touch, smell, and hearing, Sai's presence is all that remains. When a word is heard, the "heard, the hearer, and the hearing fly away; the triad shatters at once," leading to a direct, non-dual realization of Sai's all-pervading consciousness.
