What was Sai Baba's philosophy regarding physical austerities and diet, as detailed in his life story?

As described in Chapter 23, Sai Baba did not engage in the typical spiritual practices of fasting, physical austerities, or the labors of Hatha Yoga. His approach to the body was practical. He maintained his life and protected his body because he saw it as a means to liberation. He was not attached to sensory pleasures, especially taste. His only food was the daily alms (Madhukari) he received, and he consumed only a small amount. Whether the bread he received was good or plain, he considered it sweet. Chapter 23 emphasizes that he was always free of ego, and his own peace was his true ornament, not external practices or decorations.
