What is the specific role of the Satguru in helping a devotee become fearless of worldly existence?

The Satguru's role is central to overcoming fear. Chapter 37 teaches that when a devotee surrenders their body, speech, mind, and all five life-breaths to the Satguru, there is no longer any reason to fear worldly existence. The Guru is described as the one who removes everything, including the ignorance that causes fear. By holding firmly to the Guru's feet, a devotee is granted the non-dual intellect, which is the antidote to the fear that arises from a dualistic worldview. Thus, the Guru acts as the ultimate guide who dispels fear by imparting the knowledge of oneness.
