How are faith and patience related in Sai Baba's philosophy, and what is the outcome of possessing them?

In Sai Baba's philosophy, faith ('Nishtha') and patience ('Saburi') are fundamentally linked and presented as the cornerstones of a disciple's journey. Chapter 19 describes them as being 'like two sisters, dear as life to each other' and representing the 'two paise' that a Guru truly desires. Possessing these virtues is the key to pleasing the Guru and achieving spiritual progress. The outcome of cultivating patience is significant; it is described as a 'mine of virtues' that brings success, averts calamities, pushes away fear, and wards off sin and distress. A life without patience is considered 'in vain,' highlighting the critical and intertwined nature of these two qualities.
