What was Sai Baba's personal role in the daily cooking process for the Handi?

Chapter 38 describes Sai Baba's deep personal involvement in preparing food. He personally went to the grocer to purchase all the necessary ingredients, such as salt, chili, vegetables, and coconut, paying in cash on the spot. Back in the Masjid, He would undertake the main labor Himself, tirelessly grinding wheat, pulses, and millet with a grinding stone. The text also notes that He performed the work of grinding spices with great devotion and would personally adjust the fire in the hearth to ensure the food cooked properly.
