According to these passages, what is the relationship between faith, devotion, and experiencing Sai's presence?

As detailed in Chapter 2, there is a direct and powerful link between these concepts. The text explains that by listening to Sai's stories with true feeling, faith arises in the heart. Where this devotion is coupled with faith, Sai is described as being "always subservient." This state of faithful devotion is the key that unlocks higher spiritual experiences. It is through this that self-bliss comes naturally, and the devotee gains knowledge of their true form, allowing the "unperceivable, formless, and dense Consciousness" to manifest.
