Why is a person without patience considered to be in a 'pitiable state,' and what does patience protect one from?

According to the teachings in Chapter 19, a person without patience is considered to be in a 'pitiable state' because their life is rendered 'in vain,' even if they are a great scholar or possess other virtues. This is because patience is the fundamental quality that provides protection and ensures progress. The text states that patience is courage itself, which allows one to cross the ocean of worldly troubles. It actively wards off negative forces such as 'sin, distress, and poverty.' Moreover, it 'averts calamities through various means and pushes away fear and dread,' acting as a shield against life's greatest challenges and anxieties, making its absence a critical vulnerability.
