How did Sai Baba define the power and virtues of 'Saburi' or Patience?

In his discourse to the old lady, as recorded in Chapter 19, Sai Baba provided a profound definition of Patience, or 'Saburi'. He advised her not to cast it away, calling it the 'manliness of men' and a form of courage that helps one cross the ocean of worldly troubles. He elaborated that patience is a 'mine of virtues' and the 'queen of the King of Good Thoughts.' According to Baba, this single quality has the power to ward off sin, distress, and poverty, avert calamities, and push away fear. He stated that patience brings success and that a person without it, no matter how scholarly, lives a life in vain.
