There is not enough to go around. Though we may not realize it, a disproportionate amount of time we are involved in some kind of fear thought. It is shocking to discover we live as fearful primates. Fear is the single most effective tool of the dark. Without our fear the darkness would have very little influence on us.
Fear is a universal condition.
It is the great barrier to human growth. As we grow older we learn more and more fears so that by the time we reach maturity most of us are loaded with them. Unknowns create fears. When these unknowns are commonly and regularly exposed, the fears seem to diminish and disappear. In most cases this is but a temporary repression of what was never reconciled, only exposed.
