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

As detailed in Chapter 37, the Satguru plays a pivotal role in removing the fear of worldly existence. The text advises a devotee to surrender all five life-breaths (pranas) with body, speech, and mind, and to merge their intellect entirely with the Guru. When this complete surrender occurs, there is no longer any reason to worry about the world or fear its challenges, as the Guru is the one who removes all such concerns. Specifically regarding the fear of death, the Guru grants the 'non-dual intellect.' This special understanding, a gift from the Guru, helps the devotee see beyond the illusion of duality, which is the source of fear, and thus attain a state of fearlessness.
