How was Sai Baba personally involved in the process of cooking the food for the Handi?

According to Chapter 38, Sai Baba was deeply and personally involved in every stage of preparing the food for the Handi. He would personally go to the grocer to buy all the necessary ingredients, such as salt, chili, vegetables, and coconut, paying for them in cash. Back in the Masjid, he would set up the grinding stone with his own hands to grind wheat, pulses, millet, and spices. The text highlights that the main labor for the Handi was tirelessly done by Baba himself, who also managed the fire in the hearth to ensure the food cooked properly.
