What guidance does Chapter 16 offer regarding making offerings to a Sadguru and the nature of the Guru-disciple relationship?

Chapter 16 explains that a Sadguru is 'Aptakama,' meaning one whose desires are already fulfilled, so he does not need anything from a disciple. The true purpose of service is to make the disciple desireless. The chapter emphasizes that the Guru values the devotee's faith above all else. It states that if a leaf or flower is offered with sincere faith, He accepts it with great love, but if the same offering is made with pride, 'He turns His face away immediately.' Thus, the sincerity of the devotee's heart is paramount.
