What does Chapter 16 teach about the nature of a Sadguru and their relationship with a disciple, especially concerning offerings and desires?

According to Chapter 16, a Sadguru is described as being "Aptakama," meaning one whose desires are always fulfilled. The chapter poses the question of what a disciple could possibly fulfill for such a being. The answer provided is that the Sadguru actually fulfills the disciple's desire for service, thereby making the disciple desireless. A key teaching highlighted in Chapter 16 is the importance of intention. If a disciple offers even a simple leaf or flower with genuine faith, the Guru accepts it with great love. However, if the same offering is made with pride, the Guru will turn his face away, as he is an ocean of Truth, Consciousness, and Bliss who has little regard for mere outward rituals.
