—Wendy Wunder in The Probability of Miracles
A man is but the product of his thoughts what he thinks, he becomes.
There are some that only employ words for the purpose of disguising their thoughts.
Thoughts, like fleas, jump from man to man, but they don't bite everybody.
Except our own thoughts, there is nothing absolutely in our power.
