How does Baba describe the relationship between Faith (Nishtha) and Patience (Saburi)?

In the teachings found in Chapter 19, Baba portrays Faith (Nishtha) and Patience (Saburi) as being profoundly interconnected. He uses a beautiful metaphor, stating, 'Faith and Patience are like two sisters, dear as life to each other.' This illustrates that one cannot exist meaningfully without the other. He reinforces this by explaining that even a powerful Guru ultimately expects two key things from a disciple: 'strong faith at the Guru’s feet and the strength of courage which is patience.' These two qualities are presented as the fundamental pillars of a disciple's spiritual journey.
