No Room For Dust

Bodhi originally has no tree,
The mirror also has no stand.
Buddha nature is always clean and pure,
Where is there room for dust?

Buddha and I, distinct through a billion kalpas of time,
Yet not separate for one instant;
Facing each other the whole day through,
Yet not facing each other for an instant.

—Zen master Myōchō (Daitō Kokushi)
