Dogen, in a mountain Hermitage writes:

Because the mind is free
Listening to the rain
Dripping from the eaves
The drops become
One with me

The shattered universe collapses into the Moon-body. Here, not attached to anything, just being, not trying, not chasing, not escaping, things are undone and done, by themselves. In this, Mountains do walk, stone women are sweet; who said that one could do it, even in a dream? Who said that shinjin datsuraku can be fabricated, taylored, made, done? The rain will teach you.
