What was the 'inner meaning' of Sai Baba's words to the lady who felt she was too dependent to properly serve him?

The inner meaning of Sai Baba's words was to reveal the profound truth that serving any living being is equivalent to serving him directly. In Chapter 9, when the lady expressed her inability to serve him because she herself was dependent, Baba replied that he had been completely satisfied and was still belching from the bread she had offered. He then clarified that he had experienced this meal through the hungry dog she fed, stating, "that dog which you saw suddenly, I have oneness with him." This powerful teaching, described as 'supreme nectar', showed her that true service transcends personal limitations and that acts of compassion towards any creature are received by Baba himself, demonstrating his omnipresence.
