How does Sai Baba explain the connection between Faith (Nishtha) and Patience (Saburi)?

Sai Baba presents Faith (Nishtha) and Patience (Saburi) as two inseparable and essential qualities for a disciple. In Chapter 19, he reveals that these were the 'two paise' his Guru required, signifying they are the fundamental offering on the spiritual path. He emphasizes their close bond by stating, "Faith and Patience are like two sisters, dear as life to each other." This illustrates that one cannot truly exist without the other. The text further reinforces this by explaining that even a powerful Guru expects two things from a disciple: "strong faith at the Guru’s feet and the strength of courage which is patience." The two virtues work in tandem to form the foundation of a disciple's spiritual development and worthiness.
