What is the relationship between Faith (Nishtha) and Patience (Saburi) according to the teachings?

According to the teachings in Chapter 19, Faith (Nishtha) and Patience (Saburi) share an inseparable and deeply affectionate bond. Sai Baba describes them poetically as 'like two sisters, dear as life to each other.' This imagery illustrates that they are not just independent virtues but are intrinsically linked and mutually supportive on the spiritual path. The text further reinforces their combined importance by stating that even a powerful Guru expects two primary things from a disciple: 'strong faith at the Guru’s feet and the strength of courage which is patience.' This shows that both qualities are essential for a disciple's progress and are the most valued offerings one can make.
