I fear death. "Fear of death" is programmed into the most primitive lizard parts of the brain. I doubt that there has ever been a living creature with a medulla oblongata
and other parts of our early brain who does not sometimes fear death at a very primal level. Death is scary! Ask a gazelle being chased by a tiger.
One thing, though, that can be attained from all this Zen Practice ... tasting to the marrow all the Truth(s) offered ... is something that I might term "fear without fear"
... which is kind of life feeling "fear" and "no fear/fearlessness" all at once ... and is sometimes also experiencing "no fear" whatsoever when other people might be experiencing "fear" ... and is also sometimes "not fearing that sometimes we fear", because it is the natural human condition
I believe that it is the above tastes which are the unique fruits of Buddhist practice.
