Can you provide a summary of Sai Baba's teachings on the interconnectedness of faith and patience?

Sai Baba's teachings, particularly in Chapter 19, emphasize that Faith (Nishtha) and Patience (Saburi) are deeply interconnected and indispensable virtues. They are described metaphorically as the 'two paise' a disciple must give to their Guru, signifying their supreme value over any material offering. The text beautifully illustrates their bond by stating, 'Faith and Patience are like two sisters, dear as life to each other.' This suggests that one cannot fully exist without the other. While patience is lauded as a 'mine of virtues' that averts calamities and fear, it is strong faith at the Guru's feet that provides the foundation for this patience to flourish, ultimately allowing a disciple to be polished like a gem.
