What was Sai Baba's most important advice regarding charity and feeding the hungry?

Sai Baba emphasized that the highest form of service is to feed the hungry. As detailed in Chapter 9, he gave this instruction: "Know such is my mercy; give bread to the hungry first. Afterward, eat for your own stomach; keep this well in your heart." He considered this an absolute truth, spoken from the Mosque. This teaching was not just a metaphor; he explained to a devotee that when she fed a hungry dog, he himself felt satisfied and was "still getting belches," demonstrating his complete identification with the hungry and the immediate spiritual benefit of such selfless service.
