Can you elaborate on the relationship between Faith (Nishtha) and Patience (Saburi) as explained by Baba?

In the teachings found in Chapter 19, Baba presents Faith (Nishtha) and Patience (Saburi) as deeply interconnected and essential virtues for any disciple. He illustrates their bond by describing them as the "two paise" his own Guru requested, signifying their foundational value. Baba uses a beautiful metaphor, stating, "Faith and Patience are like two sisters, dear as life to each other." This highlights that one cannot exist meaningfully without the other. He confirms that even a powerful Guru expects a disciple to possess both "strong faith at the Guru’s feet and the strength of courage which is patience," indicating these twin virtues are the true offering on the spiritual path.
