How are the qualities of Faith (Nishtha) and Patience (Saburi) connected in Sai Baba's teachings?

In the teachings recounted in Chapter 19, Faith (Nishtha) and Patience (Saburi) are presented as intrinsically linked and equally vital for a disciple. They are first introduced as the 'two paise' that a Guru truly desires from a student. Their deep connection is beautifully illustrated when the text describes them as being 'like two sisters, dear as life to each other.' This implies they are inseparable and mutually supportive. The text further explains that even a powerful Guru expects 'strong faith at the Guru’s feet and the strength of courage which is patience,' reinforcing that both are required for a disciple's spiritual progress and for pleasing the Guru.
