What warnings and advice does Chapter 16 offer to a seeker on the spiritual path?

Chapter 16 provides pointed advice for spiritual seekers, emphasizing that the primary path is humble service and complete surrender to the Guru. It warns that even a slight neglect in that service or the use of one's own "cleverness" (Chaturai) will inevitably lead the seeker into trouble. The chapter strongly advises that firm faith at the Guru's feet is necessary for progress. The text reassures the devotee that the disciple does not need to know their own pitfalls, as the Guru unknowingly provides the remedy. Therefore, the ultimate refuge is to surrender exclusively to the Guru.
