According to Sai Baba's discourse in Chapter 19, why is patience considered such a vital virtue, and what are its tangible benefits?

In Chapter 19, Sai Baba elevates patience to a position of supreme importance, calling it a 'mine of virtues' and the 'queen of the King of Good Thoughts.' Its vitality stems from its power to guide a soul through life's hardships. The text lists several tangible benefits, stating that patience is the 'manliness of men' because it 'wards off sin, distress, and poverty.' Furthermore, it 'averts calamities through various means and pushes away fear and dread.' Baba promises that when a 'heavy burden falls,' patience is the single virtue that 'will take you to the other shore,' putting calamity 'to flight in twelve directions.'
