What was the spiritual purpose behind Sai Baba's practice of begging for food as described in Chapter 9?

As detailed in Chapter 9 of the Shri Sai Satcharitra, Sai Baba's lifelong habit of begging for food was a profound act performed for the spiritual welfare of his devotees. The text clarifies that this practice was for the 'removal of the Panchasuna and other sins.' The Panchasuna refers to the five unintentional sins committed in a household during daily chores. By accepting food as alms, Baba was essentially absorbing and cleansing these sins from the homes of his followers, demonstrating that his actions were always aimed at their purification and spiritual benefit.
