Why was the practice of begging for alms considered appropriate for Sai Baba?

According to the explanation in Chapter 9, begging for alms was uniquely appropriate for Sai Baba for several reasons. Firstly, he was neither a householder nor a forest-dweller, but a pure celibate and sanyasi from childhood, a state for which begging is considered commendable. Secondly, this practice allowed householders to fulfill their scriptural duty of offering food to ascetics. Most importantly, the text argues that only a "universal family member" with the firm realization of being "Vasudeva, the sustainer of the world" has the true right to live on alms, a status attributed to Sai Baba.
