"Love is the most healing force in the world, nothing goes deeper than love. It heals not only the body, not only the mind, but also the soul. If one can love then all one's wounds disappear. Then one becomes whole -- and to be whole is to be holy."

This is from an ePub book I opened at random just now.

It doesn't really matter who wrote it because, in my own experience, it is an eternal verity.
