What does Chapter 16 say about the relationship between a disciple's service and the Sadguru's desires?

Chapter 16 explains a profound and seemingly paradoxical relationship. It begins by stating that the Sadguru is 'Aptakama,' meaning all his desires are already fulfilled, so there is nothing a disciple can truly give Him to satisfy a need. The chapter then clarifies the true nature of this interaction: "The Sadguru fulfills the desire for service in the disciple and makes him desireless." This means the act of service is a grace bestowed by the Guru upon the disciple. By accepting the devotee's offering of service, which must be done with faith, the Sadguru provides a path for the disciple's spiritual purification and ultimate liberation from worldly desires.
