What was Sai Baba's personal role in the physical act of cooking the food served from the Handis?

Sai Baba was intimately involved in every physical aspect of the cooking process. Chapter 38 explains that for the sake of the Handi, the main labor was done by Baba Himself. He would personally grind wheat, pulses, millet, and spices using a grinding stone. He managed the fire, adjusting the fuel to make it mild or intense. He would put pulses to soak, knead balls of wheat flour to make large 'Pole' (flatbreads), and also prepare 'Ambil' (gruel) by mixing millet flour, water, and buttermilk in the Handi. This illustrates that He performed these tasks tirelessly and with great devotion.
