Given that he didn't fast, can you elaborate on Sai Baba's unique form of renunciation and his philosophy on bodily needs?

Sai Baba's renunciation was profound and internally focused, rather than being expressed through conventional austerities. Chapter 23 explains that although He possessed perfect renunciation, He deliberately chose not to practice fasting or Hatha Yoga. His philosophy involved maintaining the body as a vehicle for liberation. He did this by consuming a small amount of food from daily alms, demonstrating complete detachment from taste or preference. This action, coupled with His constant awareness of pervading all creation and bearing no enmity, shows that His renunciation was a state of being free from ego and desire, a state where inner peace was the only true ornament.
