The causes of hatred are legion--fear, envy, ignorance,
irrationality, the
drive toward dominance, an instinctive prejudice--to list a few.
 
In his journal, Marcus Aurelius suggests that it is in our power whether or
not to bear hatred toward another. He believed that everyone
participates in the same divine intelligence, so that to hate or to
act against one another is contrary to Nature.
 
If we act responsibily, therefore, we will summon our inner strengths and
let go of the poisons of hate. It is a waste of our efforts, emotions,
and, more importantly, time.
