How does a Sadguru handle a disciple's desire to serve him, and what is the ultimate outcome of this interaction?

Chapter 16 explains a profound dynamic between the Guru and disciple. A Sadguru is described as 'Aptakama,' meaning one whose desires are already fulfilled, so a disciple cannot actually fulfill any need for Him. Instead, the Sadguru graciously fulfills the disciple's own deep-seated desire to perform service. By allowing and accepting this service offered with faith, the Guru engages the disciple in a transformative process. The ultimate outcome, as mentioned in the chapter, is that the Sadguru uses this opportunity to make the disciple themselves become desireless.
