Here are poems for a rainy day:

WHEN I AM AMONG THE TREES
by Mary Oliver
When I am among the trees,
especially the willows and the honey locust,
equally the beech, the oaks and the pines,
they give off such hints of gladness.
I would almost say that they save me, and daily.
I am so distant from the hope of myself,
in which I have goodness, and discernment,
and never hurry through the world
but walk slowly, and bow often.
Around me the trees stir in their leaves
and call out, “Stay awhile.”
The light flows from their branches.
And they call again, “It’s simple,” they say,
“and you too have come
into the world to do this, to go easy, to be filled
with light, and to shine.”
KINSHIP
by Ursula K. Le Guin
Very slowly burning, the big forest tree
stands in the slight hollow of the snow
melted around it by the mild, long
heat of its being and its will to be
root, trunk, branch, leaf, and know
earth dark, sun light, wind touch, bird song.
Rootless and restless and warmblooded, we
blaze in the flare that blinds us to that slow,
tall, fraternal fire of life as strong
now as in the seedling two centuries ago.
