In the teachings presented in Chapter 19, Faith (Nishtha) and Patience (Saburi) are depicted as deeply interconnected and indispensable virtues. Sai Baba describes them as being 'like two sisters, dear as life to each other,' which highlights their inseparable and mutually supportive nature. The narrative suggests that while a disciple must have 'strong faith at the Guru’s feet,' it is patience that provides the 'strength of courage' to endure trials. Patience is described as the 'manliness of men' that wards off calamities, while faith provides the foundational trust. Together, they form the complete offering that a Guru expects from a disciple.
