How does Sai Baba explain the relationship between the concepts of Faith (Nishtha) and Patience (Saburi)?

In Chapter 19, Sai Baba beautifully illustrates the profound connection between Faith and Patience, describing them as being inseparable and mutually reinforcing. He states, "Faith and Patience are like two sisters, dear as life to each other." This metaphor suggests a deep, familial bond, implying that one cannot truly exist without the other. The text further elaborates that while a Guru may be powerful, what he truly expects from a disciple is "strong faith at the Guru’s feet and the strength of courage which is patience." Patience is elevated to the status of "a mine of virtues, the queen of the King of Good Thoughts," highlighting its supreme importance alongside faith in the path of a devotee.
