What is the main lesson Sai Baba is trying to teach by recounting the story of his Guru and the request for two paise in Chapter 19?

The primary lesson Shri Sai imparts through the story of his Guru in Chapter 19 is the paramount importance of two specific virtues for any spiritual seeker: Faith (Nishtha) and Patience (Saburi). By explaining that the 'two paise' his Guru requested were not money but these qualities, Baba emphasizes that a Guru's true expectation is not a material offering but the disciple's inner state. Chapter 19 elaborates extensively on the power of patience, calling it the "courage" that will carry one through life's burdens and a "mine of virtues." The story serves as a powerful illustration that a disciple's success depends on having "strong faith at the Guru’s feet and the strength of courage which is patience."
