Could you explain the concept of the Sadguru being 'Aptakama' as mentioned in Chapter 16 and how it affects his relationship with disciples?

Chapter 16 describes the Sadguru as 'Aptakama,' which means one whose desires are always fulfilled and who is, therefore, inherently desireless. The text poses the question: What can a disciple possibly fulfill for a being who is already complete? It then clarifies that the dynamic is reversed. The Sadguru, being 'Aptakama,' actually fulfills the disciple's deep desire to perform service. In doing so, the Sadguru guides the devotee along a path that ultimately makes the devotee desireless as well, thus facilitating their spiritual liberation. This concept underscores that service to the Guru is a means for the disciple's own purification and progress.
