He felt like he was getting electrocuted on a full stomach. This terrifying experience overwhelmed his entire being, making him wish for death over and over again.
This was to be expected, as he was doing this without any concrete preexisting knowledge on the subject, especially when it came to the delicate matters of the soul. Without proper guidance, this was bound to happen.

There was a reason why this stage claimed the most victims. Only those favored by fate, as well as those with sufficient preparations, could survive this stage.
