According to Chapter 38, what is the significance of food donation (Annadan), and how did Sai Baba exemplify this principle?

Chapter 38 of the Sai Satcharitra extensively discusses the supreme virtue of food donation, or Annadan. It declares that while other ages had different primary duties, charity is the key practice for the current Kali age, and Annadan is the foremost among all charitable deeds. The text poignantly states that food is the form of the Supreme Reality (Para-Brahman) from which all beings are born and sustained. As explained in this chapter, one should never turn away a hungry guest, as doing so invites downfall. The chapter explicitly mentions that Sai Baba himself followed this principle, feeding people in accordance with worldly customs, thereby demonstrating the importance he placed on this act of compassion.
