According to the provided text, what is the role of a devotee's faith and devotion in their relationship with Sai Nath?

The verses in Chapter 30 highlight that a devotee's faith is paramount. It is through the "qualities of devotees' devotion" that the formless (Nirguni) is drawn into a tangible form (Saguni). Devotees are described as becoming entranced by craving Sai's spoken words, watching with faith, and trusting completely. According to Chapter 30, this complete trust is essential because Sai Nath knows the heart's desires of his devotees and has the power to fulfill them, leading to their ultimate fulfillment. The author's own experience of his wavering mind being stilled through faith reinforces this powerful theme.
