Based on Chapter 23, what is the moral of the story involving the Yogi and Sai Baba eating onions?

The story of the Yogi in Chapter 23 serves as a crucial lesson against judging saints by their external actions or habits. The Yogi, a learned practitioner, formed a negative judgment and strong misgiving simply by seeing Baba eat bread and onions. However, Baba's omniscient reply, "One who has the strength to digest it may eat onion freely," exposed the superficiality of the Yogi's doubt. The moral, as conveyed in Chapter 23, is that a saint's true state is beyond worldly criteria like diet or caste. True faith requires looking past these externals and surrendering with a doubt-free heart, which is the only way to resolve one's inner calamities and receive the Guru's grace for attaining peace.
