What does Chapter 16 of Sai Satcharitra advise on how a devotee should approach the Sadguru?

Based on the teachings in Chapter 16, a devotee should approach the Sadguru with sincere faith and humility. The chapter explains that if a leaf or flower is offered with faith, the Guru accepts it with great love, but turns away from offerings made with pride. It emphasizes that firm faith at the Guru's feet is essential, and cleverness or neglect in service can lead to trouble. The text advises that a disciple should simply surrender themselves to the Sadguru, as the Guru is the most generous giver who provides the ultimate refuge and remedies for the disciple's unknown pitfalls.
