According to Chapter 16, what is the role of the Sadguru in a disciple's life, especially concerning the disciple's own faults and spiritual progress?

Chapter 16 portrays the Sadguru as the ultimate guide and protector on the spiritual path. It states that a disciple does not even know their own pitfalls, but the Guru unknowingly provides the remedy. This highlights the Guru's omniscient and compassionate nature. The chapter advises that a disciple's only task is to "simply surrender himself to the Sadguru." By doing so, the Guru takes responsibility for the disciple's upliftment. He is described as having taken a body for the very purpose of helping others and uplifting the poor and lowly. By serving Him with faith, the servant can attain union with Brahman, a goal that the text suggests is impossible to achieve through other means or without the Guru's grace.
