Describe the specific path to overcoming the fear of death as explained in Chapter 37.

According to Chapter 37, the great fear of worldly existence is death itself. To become fearless, one must surrender completely to the Satguru with body, speech, and mind, merging one's intellect to be subordinate to the Guru. The text advises one to 'hold firmly to the Guru’s pair of feet,' as He will grant the non-dual intellect. When one serves this non-distinguished state, there is not even a trace of fear. This surrender to the Guru is so complete that the scripture asks, 'what talk is there of the fear of worldly existence?' when the Guru is the one who removes all worries.
