How did Sai Baba describe the relationship between faith and patience in his teachings?

In the spiritual discourse from Chapter 19, Sai Baba presents Faith (Nishtha) and Patience (Saburi) as intrinsically linked and fundamentally important. He first introduces them as the two symbolic coins, or 'paise,' that his Guru requested, signifying their value above all else. He further illustrates their bond by describing them as being "like two sisters, dear as life to each other." This powerful imagery suggests that one cannot exist meaningfully without the other. He also notes that even a very powerful Guru expects a disciple to possess both strong faith at the Guru’s feet and the courageous strength that is patience.
