According to the ninth chapter, what was the spiritual significance of Sai Baba's practice of begging for food?

Chapter 9 explains that Sai Baba's lifelong habit of begging for food was not for his own needs but was performed for the spiritual welfare of his devotees. The text states that this practice was specifically for the removal of the 'Panchasuna' and other sins of the householders who gave him alms. This act is presented as a method for purifying the devotees and is linked to the broader teaching also mentioned in the chapter: that God, or Sai, is pervaded everywhere and resides in all beings. Thus, his begging was a profound spiritual exercise for the benefit of others.
