To eliminate worldly fear, which specific faculties does chapter 37 say a devotee must surrender to the Satguru?

Chapter 37 is very specific about what a devotee must surrender to the Satguru to be free from the fear of worldly existence. It calls for a total and complete surrender, listing several faculties. The text explicitly states that one must surrender with their body, speech, and mind. It further elaborates that all five pranas, or life-breaths, must also be surrendered. Finally, it mentions that even the decisive intellect should be merged and made entirely subordinate to the Guru, leaving no room for worldly worries to take hold.
