How does Chapter 19 describe the relationship and individual importance of Faith (Nishtha) and Patience (Saburi)? Are they equally important?

Chapter 19 presents Faith (Nishtha) and Patience (Saburi) as the two essential qualities a Guru desires from a disciple, describing them as the "two paise" Shri Sai offered his own Guru. They are portrayed as being deeply interconnected, like "two sisters, dear as life to each other." While they are presented as an inseparable pair, Chapter 19 dedicates significant verses to extolling the virtues of patience specifically. It is called "a mine of virtues," the "manliness of men," and a force that wards off sin, distress, and poverty. It is patience that brings success and averts calamity, suggesting that while faith is the foundation, patience is the active courage that navigates life's challenges.
