Describe the relationship between Faith and Patience as depicted in Sai Baba's teachings.

In Chapter 19, the teachings describe Faith and Patience as being intrinsically linked and vital for a disciple. They are poetically referred to as "two sisters, dear as life to each other." The text emphasizes that even a powerful Guru expects these qualities from a disciple: "strong faith at the Guru’s feet and the strength of courage which is patience." Patience is lauded as a "mine of virtues" and the "queen of the King of Good Thoughts," highlighting its supreme importance alongside faith in the spiritual journey. A human being's life is considered in vain without patience, regardless of their other virtues.
