Besides sweeping the roads, what other profound acts of self-sacrifice and devotion did Balaji Patil Nevasakar perform for Sai Baba?

Chapter 35 describes Balaji Patil Nevasakar as a devotee who performed extraordinary service and was detached from worldly possessions. Beyond his daily task of sweeping Baba's paths, his devotion was demonstrated in two other significant ways. Firstly, after every harvest, he would bring all the grain from his field to the mosque and offer it at Baba's feet. He considered Baba the true owner and would only take home the amount of grain that Baba gave back to him for his family's sustenance. Secondly, in a profound act of reverence, Balaji would wait for Baba to finish bathing and washing, and then he would drink the wastewater from the drain. This illustrates his immense self-sacrifice and deep devotion, which, as the text notes, his son partially continued by sending grain to Baba.
