It took a few years before I realized that it was the exception, not the rule, that such miraculous experiences took place. I learned that most saints were more akin to Hugh Nibley's description of his grandfather, a member of the First Presidency, who said that if he ever saw an angel he would "jump out the window."
I think such things are experienced less because we talk of them less. As we talk of them less, we increase our doubts about such things. Doubt and faith cannot coincide.
