How does Chapter 19 describe the relationship between Faith (Nishtha) and Patience (Saburi)?

Chapter 19 presents Faith (Nishtha) and Patience (Saburi) as deeply interconnected and essential qualities for a disciple. They are not just abstract virtues but are personified as 'two sisters, dear as life to each other.' This metaphor suggests an inseparable bond and mutual reliance. The chapter explains that these were the 'two paise' Sai Baba gave to his Guru. Furthermore, it is stated that a Guru, no matter how powerful, expects 'strong faith at the Guru’s feet and the strength of courage which is patience' from the disciple. This shows that faith provides the foundation of trust in the Guru, while patience provides the endurance to see the spiritual process through to its fruition.
