How does Chapter 16 describe the relationship between a Sadguru's desires and a disciple's desire for service?

Chapter 16 provides a profound insight into the Guru-disciple dynamic regarding desires. It states that a Sadguru is always 'Aptakama,' meaning one whose desires are already fulfilled, so there is nothing a disciple can truly give Him to satisfy a need. Instead, the relationship is reversed. The Sadguru's role is to fulfill the disciple's innate desire to perform service. By accepting the devotee's service, which is offered out of faith, the Guru helps the disciple on their spiritual path. As explained in Chapter 16, this process ultimately guides the disciple towards becoming desireless themselves, which is a key goal of spiritual evolution.
