It does seem a strange thing to count suffering as joy, yet there's a truth here in that suffering helps to build one's character. Some of the most beautiful people I know are those who have passed through the flames and come out strengthened. If it happens to clay, why shouldn't it happen to us.
Much of our work is invisible and intangible. You cannot measure it by human means; and sometimes a period of silent reflection will accomplish more good than if the time had been spent in outward activity. Our work is immaterial where we are and what we do; the thing that matters is who we are and what we intend. Constant preoccupation with exterior work handicaps our knowledge of ourselves and of our intentions.
