Based on Chapter 16, how does a Sadguru interact with devotees and guide them towards knowledge?

As detailed in Chapter 16 of the Sai Satcharitra, a Sadguru, despite being an 'ocean of Truth, Consciousness, and Bliss,' engages deeply with his followers. He takes a physical form to uplift the poor and lowly. The text explains that he sometimes dons a 'cloak of ignorance' in order to impart knowledge to the ignorant, providing sweet and gentle instruction without transgressing proper conduct. He accepts offerings like a simple leaf or flower with great love when given with faith, but will turn away from the same offering if it is presented with pride. This shows that the Guru values the inner state of the devotee over outward rituals, even while enjoying rituals done with sincere faith.
