What does Chapter 16 of the Sai Satcharitra say about how a devotee should serve the Sadguru?

According to Chapter 16 of the Sai Satcharitra, a disciple's approach to the Sadguru should be rooted in sincere faith and humility. The chapter emphasizes that the Guru accepts offerings, even a simple leaf or flower, if given with love, but will turn away from anything offered with pride. It warns against using 'cleverness' in service, as it can lead the seeker into trouble. The most crucial action for a disciple is to completely surrender to the Sadguru. As the text explains, the disciple often doesn't know their own pitfalls, but the Guru provides the necessary remedy, making firm faith and humble service the only means that will not fail.
