Based on Chapter 38, what is the philosophical and practical basis for the emphasis on feeding others?

Philosophically, Chapter 38 establishes food as the embodiment of Para-Brahman, the Supreme Reality. It states that food is the source from which all beings originate, the means by which they survive, and the substance into which they merge at the end. Practically, the text appeals to a common human experience, noting that at midday, the life-force becomes restless without food. It suggests that a truly good person is one who understands that this feeling is the same for everyone. Therefore, turning away a guest who asks for food is said to invite one's own downfall, making food donation a critical spiritual and ethical duty.
