How did Balaji Patil Nevasakar demonstrate his self-sacrifice and devotion to Sai Baba?

Balaji Patil Nevasakar demonstrated profound self-sacrifice and devotion through several extraordinary acts of service. Chapter 35 details how he would sweep the paths that Baba walked daily. His detachment from worldly possessions was shown when he would bring his entire harvest to the mosque, offering it at Baba's feet and only taking home the portion that Baba gave back to him. In a remarkable display of reverence, he would drink the wastewater from the drain after Baba had bathed. This level of devotion was a continuous practice throughout his life.
