The text from Chapter 35 talks about the 'triad' of the seen, seer, and seeing vanishing. What does this philosophical concept mean?

This concept, described in Chapter 35, refers to the attainment of a state of non-duality through devotion to Sai. The 'triad' represents the separation we normally feel between the observer (the 'seer'), the object being observed (the 'seen'), and the act of observation ('seeing'). The text explains that for a true devotee, the experience of Sai through the senses is so complete that this separation dissolves. For example, a glance at Sai is enough to take away hunger and thirst. When a word is heard, Sai's form manifests, and the triad of the 'heard, the hearer, and the hearing' shatters. As Chapter 35 states, this same principle applies to all senses and actions, leading to a state where only the all-encompassing presence of Sai remains, erasing duality.
