What was Baba's advice on eating habits? Was he only against fasting or was there more to it?

Sai Baba's advice on eating was nuanced and focused on moderation rather than just a simple rule against fasting. Chapter 32 clarifies that while he considered excessive fasting to be "terrible" and a cause of "continuous discomfort," he also taught that "excessive eating is also not beneficial." His core teaching on the matter was that "moderate eating is truly comfortable." This indicates a balanced approach, steering devotees away from the extremes of both deprivation and gluttony. The ideal state, for both physical comfort and spiritual readiness, was to be found in moderation.
