Based on Chapter 16 of the Sai Satcharitra, what is the proper way for a disciple to approach and serve their Sadguru?

Chapter 16 provides clear guidance on the disciple's conduct. It emphasizes that a disciple should approach the Sadguru with sincere faith and humility, not pride. The text states that if a leaf or flower is offered with faith, the Guru accepts it with love, but turns away from offerings made with pride. The most crucial action for a disciple is to simply surrender themselves completely to the Sadguru. Chapter 16 warns against using "cleverness" or showing even slight neglect in service, as this will lead to trouble. The surest path to spiritual union is through faithful, humble service at the Guru's feet.
