Napowrimo Day 14 Not a san san

Deep in the green.
Deep in the forest between the vast urban sprawl.
Carpeting the leaf scattered floor,
Reaching between tall pillars.
An ancient cathedral of trees.
It grows.
Thick, and rich with memory.
Nurturing, and long lived with mystery
It grows.
Soft, sun tickled, flourishing.
Protecting nature's past.
Hiding humans past.
Preserving all that is past
with its enveloping blanket of verdant green,
Moss slowly grows.

The prompt to day was for a san san but my brain hurts so you only get a green poem instead. But I want to remember what it is so I can try when less exhausted.
Why does work always get in the way of words?

"Today’s prompt comes to us from TJ Kearney, who invites us to try a seven-line poem called a san san, which means “three three” in Chinese (It’s also a term of art in the game Go). The san san has some things in common with the tritina, including repetition and rhyme. In particular, the san san repeats, three times, each of three terms or images. The seven lines rhyme in the pattern a-b-c-a-b-d-c-d.

Here’s an example san san from TJ’s blog, Bag of Anything:

Drinking the driven storm, the sturdy apple
Dances, between sky and earth, her spring-young leaves.
Knowing no purpose, knowing only season,
Her spring-young leaves, storm-driven, dapple
Earth and sky; all that my eye perceives
Dances. My eye drinks in the apple’s spring-
Young leaves, her dance that has no reason:
Only the storm, driving each dappled thing.

As you can see, three images or terms are repeated: the driven storm; the spring-young leaves; the dance, and the seven lines rhyme per the pattern given above." (from Napowrimo2016 day 14 prompt)
