What guidance does this chapter provide on the proper way for a disciple to approach a Sadguru, and what potential pitfalls should be avoided?

According to the teachings in Chapter 16, the most crucial element in approaching a Sadguru is faith. A disciple should offer service and devotion with sincere faith, as the Guru accepts even a simple leaf offered with love but rejects anything given with pride. The text explicitly warns against using "cleverness" (Chaturai) or showing even slight neglect in service, as these actions lead the seeker into trouble. Ultimately, the chapter advises that a disciple should simply surrender themselves completely to the Sadguru, trusting that the Guru knows their pitfalls and will provide the necessary remedy.
