Adho Mukha Svanasana--Downward Facing Dog

The inchworm angles
upward, its back end
lagging, to inspect a leaf.
In this pose, I am stillness
set in motion, legs like young
oaks, with all their secret life
beneath the skin. Half of me
insists on earth, feet wedded
to the floor--the other
half aspiring to the sky, the spine
yearning for what it's not,
while the arms, those mediators,
lie somewhere in between, and the head
a full moon among clouds.
