What guidance does Chapter 16 offer to a disciple regarding service, faith, and the use of 'cleverness'?

In Chapter 16, the guidance for a disciple is very clear: one must simply surrender to the Sadguru with firm faith. The text warns that even a slight neglect in service or the use of 'cleverness' (Chaturai) will lead the seeker into trouble. The Sadguru accepts offerings like a leaf or flower with great love when given with faith, but turns away from anything offered with pride. It is emphasized that through faithful service, a servant can attain union with Brahman, but this path requires humility, as the disciple often does not even know their own pitfalls, which the Guru unknowingly remedies.
