How does Sai Baba describe the power and importance of patience, or Saburi?

In Chapter 19, Sai Baba extensively details the profound importance and power of patience, which he calls Saburi. He describes patience as the very 'manliness of men' and a form of courage that helps one overcome great burdens and reach the 'other shore.' According to the text, patience is a potent force that wards off sin, distress, poverty, and fear, while averting calamities. It is hailed as a 'mine of virtues' and the 'queen of the King of Good Thoughts.' Baba emphasizes that a human being's life, even if they are a great scholar, is in vain without patience, highlighting it as an indispensable quality for any spiritual aspirant.
