According to chapter 37, who is the one that can remove the fear of worldly existence and death?

The text in chapter 37 identifies the Satguru as the one who removes the fear of worldly existence. By surrendering one's body, speech, mind, life-breaths, and intellect entirely to the Guru, all worries about the world are eliminated. The chapter explicitly states that to become fearless from death, which is the great fear of worldly existence, one should hold firmly to the Guru’s pair of feet. The Guru will then grant the non-dual intellect, which removes the fear that arises from duality and the perception of manifoldness.
