In what ways did Balaji Patil demonstrate his detachment from worldly possessions and his complete self-sacrifice for Sai Baba?

Balaji Patil exemplified a life of being in the world but detached from it through incredible self-sacrifice. Chapter 35 explains that after each harvest, he would bring his entire yield of grain to the mosque, offering the heaps at Baba's feet. He considered Baba the true owner and would only take home the portion that Baba gave back to him. In another extreme act of devotion, Balaji would drink the wastewater from the drain after Baba had bathed and washed. This illustrates his profound level of renunciation and dedication.
