How did Sai Baba personally involve himself in the process of cooking food for his devotees?

According to Chapter 38, Sai Baba was intimately involved in every stage of preparing food. He would personally go to the market to purchase all the necessary ingredients like vegetables, coconut, salt, and spices, always paying in cash. He undertook the main labor himself, tirelessly grinding wheat, pulses, and millet using a grinding stone he set with his own hands. He also ground the spices with great devotion and personally managed the cooking fire, adjusting the fuel to control the heat. This deep, personal involvement highlights his commitment to feeding the hungry, as described in the chapter.
