How does Sai Baba describe the virtues and power of patience?

In Chapter 19, patience, or Saburi, is described as a virtue of immense power and significance. It is equated with courage, being called 'the manliness of men' that helps one overcome heavy burdens. The text states that patience is a 'mine of virtues' and the 'queen of the King of Good Thoughts.' Its practical benefits are extensive, as it is said to ward off sin, distress, and poverty, avert calamities, and push away fear. Ultimately, patience is presented as a key to success and a foundational quality, as the text laments that a life without it, regardless of one's knowledge or virtue, 'is in vain.'
