How does the text describe the relationship between Faith (Nishtha) and Patience (Saburi)?

The source material from Chapter 19 portrays Faith (Nishtha) and Patience (Saburi) as intrinsically linked and equally vital for a disciple. They are first introduced as the 'two paise' required by the Guru, signifying their foundational importance. The text deepens this connection by stating, "Faith and Patience are like two sisters, dear as life to each other." This powerful simile illustrates their inseparable and mutually supportive nature. It is also mentioned that even a very powerful Guru expects their disciple to possess "strong faith at the Guru’s feet and the strength of courage which is patience," reinforcing that both qualities are essential for spiritual growth.
