"Teach me mortality, frighten me
into the present, Help me to find
the heft of these days."
If ever there was a prayer that I should say every day, this is it.
On a purely stylistic note, I absolutely love his choice of "heft" instead of "weight". Completely different connotations in this context. Weight holds us down, requires strength to maneuver. Whereas Heft has the duality of functioning as both a noun and verb, thereby not immediately attaching itself to its root meaning of weight, but also of action and active engagement in the moment.
