What does Chapter 16 say about the nature of a Sadguru and their relationship with a disciple's desires?

Chapter 16 explains that a Sadguru is 'Aptakama,' one whose desires are already fulfilled, so a disciple cannot truly give the Guru anything he needs. The dynamic is reversed: the Sadguru fulfills the disciple's desire for service, and in doing so, guides the disciple towards becoming desireless themselves. The text also provides insight into the Guru's teaching method, stating that Baba dons a "cloak of ignorance" to impart knowledge to the ignorant. This means he relates to people on their level, giving sweet instruction without transgressing the boundaries of proper conduct, all for the disciple's upliftment.
