How does the experience of a devotee, for whom Sai's glance is sufficient, illustrate the transcendence of physical needs?

The text illustrates the transcendence of physical needs by showing how spiritual fulfillment can completely supplant them. In chapter 35, a devotee's experience is described where a single glance from Sai Baba brings total satisfaction and happiness. The passage explains this phenomenon by stating, "When there is the happiness of just one glance, we do not need food or water; The glance itself takes away thirst and hunger." This shows that the spiritual nourishment and mercy flowing from Baba's gaze are so potent and all-encompassing that they render physical necessities like food and water irrelevant. The devotee's consciousness is elevated to a state where spiritual bliss overrides the normal demands of the body, showcasing a profound aspect of the saint's grace.
