Why is Patience (Saburi) considered so important in the teachings found in Chapter 19?

In the teachings of Chapter 19, Patience (Saburi) is elevated to a status of supreme importance. It is described not merely as waiting, but as a form of courage and 'the manliness of men.' This virtue is presented as a powerful tool that can take a person 'to the other shore' when faced with heavy burdens. The chapter explicitly states that patience 'wards off sin, distress, and poverty' and 'pushes away fear and dread.' It is called a 'mine of virtues' and the 'queen of the King of Good Thoughts.' The text goes so far as to say that a life without patience, even for a learned scholar, is a life lived in vain, underscoring its foundational role in spiritual and worldly success.
