How did a devotee's experience of perception change to be entirely focused on Sai, according to the text?

According to Chapter 35, a devotee's perception can become so focused on Sai that the physical world's needs and the separation between senses and objects dissolve. The text explains that the happiness from just one glance of Sai can take away thirst and hunger, making food and water unnecessary. This experience of oneness extends to all senses. In the sense of touch, there is Sai's light; in the nose and scent, Sai resides. When a word falls on the ears, Sai's form immediately manifests, and the distinctions between the heard, the hearer, and the act of hearing shatter. Similarly, where the tongue finds taste, Sai is equally mingled there. When all the organs of action serve Sai in this way, actions themselves dissolve, leading to a state of non-action (Naishkarmya).
