Triolet: Epistemology of rain

Rain hammers the leaves; the lilac trembles from without and within.
And life’s requirements knock on every surface, asking to be taken in,
wed, fed, fattened. No frailty wants orphaning, no hurt forsaking.
Rain hammers the leaves; the lilac trembles from without and within:
such downpour makes all surfaces open pathways, yoking core to skin.
What larger thing comes to win, to teach its lesson on surrender, yielding?
Rain hammers the leaves; the lilac trembles from without and within:
and life’s requirements knock on every surface, asking to be taken in.
