According to the teachings, what is the relationship between surrendering to a Guru and overcoming the fear of worldly existence?

The teachings in Chapter 37 explain a direct correlation between surrender and fearlessness. When you surrender your body, speech, mind, and even your decisive intellect entirely to the Satguru, there is no longer any reason to fear worldly existence. This is because the Guru takes on the burden of removing all worries. The source of fear is identified as duality and ignorance (Avidya), which create the perception of manifoldness. By holding firmly to the Guru's feet, one is granted a non-dual intellect, which is inherently free from fear. Thus, complete surrender is presented as the definitive path to becoming fearless.
