What is the role of a Sadguru and the proper attitude of a disciple as outlined in Chapter 16?

Chapter 16 explains that the Sadguru is 'Aptakama,' or one whose desires are always fulfilled, and He in turn makes the disciple desireless by fulfilling their desire for service. The text emphasizes that a disciple should offer things with faith and love, not pride, as the Guru accepts even a simple leaf or flower offered with sincerity. As detailed in this chapter, the most important action for a disciple is to simply surrender completely to the Sadguru. The text warns against using 'cleverness' or neglecting service, stating that firm faith at the Guru's feet is the only way to avoid trouble and attain union with Brahman.
