What is the proper attitude for a disciple when approaching a Sadguru, based on the teachings in Chapter 16?

According to Chapter 16, the most crucial attitude for a disciple is one of complete and humble surrender. The text warns that using "cleverness" or showing even slight neglect in service will lead a seeker into trouble. Instead, a disciple should have firm faith at the Guru's feet. The chapter explains that the Sadguru accepts a simple leaf or flower offered with faith and love, but turns away from offerings made with pride. Ultimately, the guidance from this chapter is that by serving with faith, a disciple can attain union with Brahman, but this requires abandoning ego and surrendering to the Guru's wisdom.
