The sad is so big I can't get it all out

This is a magnificent poem  

Oh Wonder     by Traci Brimhall

It’s the garden spider who eats her mistakes
at the end of day so she can billow in the lung
of night, dangling from an insecure branch

or caught on the coral spur of a dove’s foot
and sleep, her spinnerets trailing radials like
ungathered hair. It’s a million-pound cumulus.

It’s the stratosphere, holding it, miraculous. It’s
a mammatus rolling her weight through dusk
waiting to unhook and shake free the hail.

Sometimes it’s so ordinary it escapes your notice—
pothos reaching for windows, ease of an avocado
slipping its skin. A porcelain boy with lamp-black

eyes told me most mammals have the same average
number of heartbeats in a lifetime. It is the mouse
engine that hums too hot to last. It is the blue whale’s

slow electricity—six pumps per minute is the way
to live centuries. I think it’s also the hummingbird
I saw in a video, lifted off a cement floor by firefighters

and fed sugar water until she was again a tempest.
It wasn’t when my mother lay on the garage floor
and my brother lifted her while I tried to shout louder

than her sobs. But it was her heart, a washable ink.
It was her dark’s genius, how it moaned slow enough
to outlive her. It is the orca who pushes her dead calf

a thousand miles before she drops it or it falls apart.
And it is also when she plays with her pod the day
after. It is the night my son tugs at his pajama

collar and cries: The sad is so big I can’t get it all out,
and I behold him, astonished, his sadness as clean
and abundant as spring. His thunder-heart, a marvel

I refuse to invade with empathy. And outside, clouds
groan like gods, a garden spider consumes her home.
It’s knowing she can weave it tomorrow between

citrus leaves and earth. It’s her chamberless heart
cleaving the length of her body. It is lifting my son
into my lap to witness the birth of his grieving.
