What does Chapter 16 say about the nature of a Sadguru and how a disciple should approach them with offerings and service?

According to Chapter 16, a Sadguru is described as 'Aptakama,' meaning one whose desires are already fulfilled and who needs nothing from a disciple. The purpose of a disciple's service is actually to help the disciple become desireless. The text emphasizes the importance of the devotee's inner state, explaining that the Guru will lovingly accept a simple leaf or flower offered with faith. However, if the same offering is made with pride, He will turn away. Though He is an ocean of Truth and Consciousness beyond rituals, He still enjoys them with satisfaction when they are performed with sincere faith.
