How does Chapter 16 describe the Sadguru's role in helping a disciple become desireless?

Chapter 16 explains a profound aspect of the Guru-disciple relationship by stating that a Sadguru is always 'Aptakama,' meaning one whose desires are already fulfilled. Therefore, a disciple cannot truly fulfill any material need for Him. Instead, the dynamic is reversed: the Sadguru is the one who 'fulfills the desire for service in the disciple and makes him desireless.' This teaching from Chapter 16 suggests that by engaging the devotee in selfless service performed with faith, the Guru purifies the devotee's mind, ultimately guiding them to a state free from worldly wants and attachments, which is a crucial step in spiritual progress.
