You have done enough (just now)

Do not worry yourself
about tardiness now. Creep about
warily. Observe the shadows, and practice
merging with them. Occupy yourself
as a watchful spirit haunting this world,
whose emanations glow
and penumbras deepen
in the hearts and minds
of all who know you, even
when you are not an active principle.
The shape and furrow you've left
streaming through only reinforces
and encourages us
in our wake
from you.
