Jumper

Roots and vines that crawl along
This lowly bower, stumbling
On the sky, flexing tendril,
Stump and stem as you set
Amorphous skill
Against the highest rung,
Young and automatic,
Building spring and power,
Unconscious of the kill,
Break out, run,
And take your one
Striding, humble,
But ecstatic leap to sun.
