How does Chapter 9 explain the spiritual significance of Sai Baba's practice of begging for food?

Chapter 9 of the Sai Satcharitra explains that Sai Baba's habit of begging for food was not for his personal sustenance but was a profound spiritual act for the benefit of his followers. The text states that Baba continued this practice until the very end of his life for the welfare of his devotees and for the removal of their sins, including the 'Panchasuna' (five inadvertent sins of household life). This act was a form of Baba's mercy, designed to impress upon people the fundamental truth that God resides in all beings and to provide a pathway for devotees to achieve their own welfare through service and devotion, as detailed in this chapter.
