Can you explain the non-dualistic perspective on suffering described in the Shri Sai Satcharitra and the idea of transcending the 'triad'?

Chapter 35 of the Shri Sai Satcharitra delves into an advanced, non-dualistic state where the suffering of separation ceases. It explains that for a true devotee, Sai's presence permeates all senses. For instance, when seeing, the distinction between the seer, the object seen, and the act of seeing vanishes because Sai is recognized as the subject of every vision. Similarly, when a word is heard, Sai's form immediately manifests, and the triad of the hearer, the heard, and the hearing shatters. This collapse of the triads, as described in Chapter 35, erases the place of duality, which is the root of perceived separation and suffering, leading to a state of unity.
