According to Chapter 38, what is the significance of food donation (Annadan) and how is it described?

According to the teachings in Chapter 38, food donation, or Annadan, is presented as the highest and most important virtue, especially for the current Kali age. The chapter states that 'food donation is the chief and foremost' among all codes of conduct. Its significance is elevated by the philosophical concept that food is the very form of Para-Brahman (the Supreme Reality), from which all beings are born and sustained. The text emphasizes its universal applicability, noting that unlike other gifts, food should be offered to anyone at any time without hesitation. As highlighted in Chapter 38, this practice was personally followed by Sai Baba, confirming its great merit.
