According to the provided texts, what is the relationship between Faith and Patience?

As detailed in Chapter 19, Sai Baba presents Faith (Nishtha) and Patience (Saburi) as deeply interconnected and equally vital virtues. He describes them as being "like two sisters, dear as life to each other." This simile suggests an inseparable bond and mutual reliance. The text reinforces this by stating that a powerful Guru expects both from a disciple: "strong faith at the Guru’s feet and the strength of courage which is patience." They are the foundational "two paise" that a disciple must offer, indicating that one without the other is incomplete for spiritual progress.
