How does Chapter 38 explain the significance of food donation, or Annadan?

Chapter 38 of the Sai Satcharitra places immense importance on the practice of food donation, known as Annadan. The chapter explicitly states that while different ages had their principal virtues—penance, knowledge, and sacrifice—the primary virtue for the Kali age is charity. Among all forms of charity, food donation is declared the "highest secret for quenching hunger" and the "foremost among all deeds." The text elevates food to a divine status, calling it the form of Para-Brahman (the Supreme Reality), from which all beings are born and into which they eventually merge. As explained in Chapter 38, it is a householder's duty to feed any guest who arrives, regardless of the time, and failing to do so invites downfall.
