How are Faith (Nishtha) and Patience (Saburi) described in relation to each other, and what is expected from a disciple even if their Guru is very powerful?

In Chapter 19, Faith (Nishtha) and Patience (Saburi) are portrayed as deeply interconnected and essential qualities for a disciple. They are described metaphorically as "two sisters, dear as life to each other," highlighting their inseparability. The text emphasizes that even if a Guru is exceptionally powerful, they still expect certain qualities from the disciple. Specifically, the Guru looks for the disciple's wisdom, which manifests as "strong faith at the Guru’s feet and the strength of courage which is patience." This indicates that a disciple's spiritual journey is a collaborative effort, requiring their active contribution of faith and perseverance, not just passive reception of the Guru's power.
