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

In the latter portion of Chapter 35, the author describes a profound state of non-dual consciousness centered on Sai. This experience involves the collapse of the separation between the observer, the observed, and the act of observation. The text states that when the subject of vision is Sai, "The triad of the seen, the seer, and the seeing vanishes, erasing the place of duality." This same principle applies to other senses. For instance, when a word is heard, Sai's form immediately manifests, and the "heard, the hearer, and the hearing fly away; the triad shatters at once." This illustrates a state where Sai's presence permeates all perception, leading to a unified, non-dual experience.
