What was the core teaching Sai Baba imparted about service and devotion when he told the lady to 'give bread to the hungry first'?

The core teaching Sai Baba imparted was a profound lesson on universal compassion and the nature of true worship. In Chapter 9, he instructs, "give bread to the hungry first. Afterward, eat for your own stomach; keep this well in your heart." This was not just practical advice but a spiritual directive. He revealed that by feeding a hungry dog, the lady had directly fed him, stating his oneness with all creatures, including dogs and pigs. His ultimate message was to transcend dualistic thinking: "He who sees me in all beings, know him to be the one I love. Therefore, you renounce the sense of difference; thus alone worship me." Devotion, therefore, is not confined to a single form but is expressed through serving the divine presence in all of creation.
