What does Chapter 16 reveal about the relationship between a Sadguru and a disciple, particularly regarding desires and offerings?

According to Chapter 16 of the Sai Satcharitra, the Sadguru is 'Aptakama,' meaning one whose desires are already fulfilled and who needs nothing from a disciple. Instead of the disciple fulfilling the Guru's needs, the Sadguru fulfills the disciple's desire for service, ultimately making the disciple desireless. The chapter emphasizes the importance of sincerity in offerings, stating that if a simple leaf or flower is offered with faith, Baba accepts it with great love. However, if the same offering is made with pride, He turns His face away, showing that the inner attitude of the devotee is what truly matters.
