In love with this sentiment of yours, my friend!
In one of my works that I named "On Suffering and the End of Suffering", I shared Buddhism teaching around suffering and the end of it. Then, I explored their findings and linked them to re-writing the subconscious program.
One of the causes was "The Fear of Death", indeed. Here were my thoughts about it:
When you reconnect with the original being, you will most probably experience the following:
I don’t want to die, but I’m not afraid. The reason is straightforward: living by principles, being on a mission much bigger than my small self, and impacting even one person’s life is making every single lived moment matter, and that would be enough to welcome death with open arms!
