What was Sai Baba's reaction to the Yogi's unspoken doubt in Chapter 23, and what does this incident reveal about Baba's character?

In Chapter 23, when the Yoga practitioner silently doubted Baba's spiritual capacity upon seeing Him eat stale bread and onions, Baba's reaction was subtle yet profound. Instead of confronting the Yogi, the omniscient Sai Maharaj addressed Nanasaheb Chandorkar and remarked, "Nana, only those whose digestion is strong should eat onion. One who has the strength to digest it may eat onion freely." This incident reveals key aspects of Baba's character. It demonstrates His omniscience, or all-knowing nature, as He was aware of the Yogi's private thoughts. It also highlights His unique teaching method, as described in Chapter 23; He guided the practitioner toward humility and understanding indirectly, without causing embarrassment. This compassionate and insightful approach startled the Yogi into surrendering his ego and doubt, ultimately leading him to peace.
