According to Chapter 9, what were the underlying reasons for Sai Baba's lifelong practice of begging for food?

The introductory verses of Chapter 9 of the Sai Satcharitra explain the profound spiritual reason behind Sai Baba's lifelong habit of begging for food. The text clarifies that this practice was not for his own needs but was undertaken entirely for the welfare of the devotees. Specifically, it was for the "removal of the ‘Panchasuna’ and other sins" of the householders from whom he accepted alms. By doing so, he was purifying them and their homes. This act, as described in Chapter 9, was a manifestation of his immense compassion and his unique method of working for the spiritual upliftment and benefit of his followers, which he continued until the very end of his life.
