What exactly did Sai Baba teach about the virtue of patience, or Saburi? It seems like it was a really big deal for him.

In Chapter 19, Sai Baba provides a profound discourse on the importance of patience (Saburi). He describes it as the 'manliness of men' and a form of courage that should never be abandoned, as it is what will take one 'to the other shore' when heavy burdens fall. He elaborates that patience is a 'mine of virtues' and the 'queen of the King of Good Thoughts.' Its power is extensive: it wards off sin, distress, and poverty, averts all kinds of calamities, and pushes away fear. Baba warns that a person without patience, regardless of their knowledge or virtue, leads a life in vain.
