In Chapter 19, Baba mentions 'Faith' and 'Patience' as two essential virtues. How does he describe the relationship between them and their importance for a disciple?

In the teachings from Chapter 19, Sai Baba presents Faith (Nishtha) and Patience (Saburi) as the two most essential offerings a disciple can give to a Guru. He reveals that these were the 'two paise' his own Guru requested from him. Baba describes their deep connection by calling them 'two sisters, dear as life to each other.' He clarifies that even a very powerful Guru expects these two qualities from a disciple above all else: 'strong faith at the Guru’s feet and the strength of courage which is patience.' A life devoid of patience, he warns, is ultimately in vain, highlighting their critical and interconnected importance on the spiritual path.
