Chapter 9 mentions that Sai Baba's practice of begging for food was for the welfare of his devotees. How does the text elaborate on this concept?

Chapter 9 explains that Sai Baba's habit of begging for food, which he maintained until the end of his life, was not for his own sake but held a profound spiritual purpose for his followers. The text explicitly states that this practice was for the removal of the ‘Panchasuna’ (five types of sins committed in a household) and other sins of the devotees from whom he accepted alms. By doing so, he was purifying their homes and their lives. This teaching, as presented in Chapter 9, is linked to the greater philosophical idea that Sai is pervaded everywhere and that God resides in all beings, making the act of giving and receiving food a sacred exchange for the spiritual welfare of the devotees.
