From our salty tears to the minerals making up our bones and tissues, our body is made up in large part of good salts. When a body is cremated, the water evaporates and what is left is salt or ashes (minerals).
Cause vs. Effect
When there is a problem in your body, your immune and other builtāin systems do the repairing. Your body is amazing! Its engineering could not be more perfect and could not be replicated by anything man made. Only nature or whatever higher power you believe in, could create something so amazing!
