In the story from Chapter 23, how did Sai Baba resolve the Yogi's unspoken doubt, and what was the outcome?

The account in Chapter 23 demonstrates Sai Baba's omniscience. Sensing the Yogi's internal conflict about Him eating onions, Baba remarked to Nanasaheb Chandorkar, "Nana, only those whose digestion is strong should eat onion. One who has the strength to digest it may eat onion freely." As this chapter explains, hearing his specific, unspoken doubt being addressed so directly startled the Yogi. His skepticism vanished, and he surrendered with true devotion. Subsequently, he sat near Baba with a doubt-free heart, his doubts were resolved, and he returned home happy after receiving Udi and a blessing.
