A certain day became a presence to me;
there it was, confronting me--a sky, air, light:
a being.  And before it started to descend
from the height of noon, it leaned over
and struck my shoulder as if with
the flat of a sword, granting me
honor and a task,  The day's blow
rang out, metallic--or it was I, a bell awakened,
and what I heard was my whole self
saying and singing what it knew: I can.
