How does Baba describe the virtue of patience and why is it so important?

Sai Baba elevates patience to a supreme virtue in Chapter 19. He describes it as courage, stating, "Patience is courage, O lady; do not cast it far away; whenever a heavy burden falls, this alone will take you to the other shore." He further elaborates that patience is the "manliness of men" because it effectively wards off sin, distress, and poverty while pushing away fear and dread. Baba calls patience a "mine of virtues" and the "queen of the King of Good Thoughts." Its importance is underscored when he says that a life without patience is in vain, even for a scholar or a person of great virtue, highlighting it as an essential quality for a meaningful existence and spiritual success.
