Can you explain the state of non-duality and sensory experience for a devotee as described in the Satcharitra?

Chapter 35 describes a profound state of union for an advanced devotee, where all senses perceive only Sai Baba, leading to the dissolution of duality. For such a person, a mere glance from Sai quenches all hunger and thirst. The triad of the seer, the seen, and the act of seeing vanishes, leaving only the experience of Sai. This applies to all senses: the sense of touch feels Sai's light, the nose smells only Sai's presence, and a word falling on the ears immediately manifests Sai's form, shattering the triad of hearer, heard, and hearing. When all senses and actions are thus dedicated to Sai, all actions dissolve, and the devotee attains Naishkarmya, the state of non-action.
