According to Chapter 19, what is the relationship between the virtues of Faith and Patience?

Chapter 19 presents Faith (Nishtha) and Patience (Saburi) as being fundamentally interconnected and equally essential for a devotee. The text uses a beautiful metaphor, stating that Faith and Patience are 'like two sisters, dear as life to each other.' This imagery suggests they are inseparable, mutually reinforcing, and should be cultivated together. The chapter further explains that a Guru expects a disciple to possess both 'strong faith at the Guru’s feet and the strength of courage which is patience.' This pairing forms the core of the 'two paise' Baba offered his Guru, signifying that one without the other is incomplete on the spiritual path.
