How does Baba describe the virtue of patience, and why does he consider it so important?

In Chapter 19, Sai Baba describes patience, or Saburi, as a supreme virtue and the "manliness of men." He emphasizes its importance by explaining that it wards off sin, poverty, and distress, averts calamities, and pushes away fear. He poetically refers to patience as a "mine of virtues" and the "queen of the King of Good Thoughts." Baba considers it so crucial that he states a person without patience, whether a scholar or otherwise virtuous, is in a pitiable state and their life is in vain. He links it intrinsically with faith, calling them two sisters who are as dear as life to each other.
