I take my guidance from the forests, who teach us something about change. The forces of creation and destruction are so tightly linked that sometimes we can't tell where one begins and the other leaves off. A long-lived overstory can dominate the forest for generations... But... something always happens that is more powerful than that overstory... A whole new ecosystem rises to replace that which no longer works in a changed world...
Nothing is more difficult than prayer. In all other tasks of spiritual life, however exacting, one can sometimes rest, but there is no rest in prayer, up to the end of one's life.
