Can you elaborate on the concept of 'Saburi' or Patience based on the provided text?

The text in Chapter 19 describes Patience, or Saburi, as a foundational and powerful virtue. It is equated with courage, stating that 'Patience is courage' and that it is the 'manliness of men.' This quality is essential for overcoming life's challenges, as it 'will take you to the other shore' when a 'heavy burden falls.' Furthermore, patience is portrayed as a protective force that 'wards off sin, distress, and poverty' and 'pushes away fear and dread.' Chapter 19 elevates it to a 'mine of virtues' and the 'queen of the King of Good Thoughts,' emphasizing that a person's life, no matter how learned or virtuous they are, is 'in vain without it.'
