The body is like the sacred bodhi tree,
The mind like a clrearly reflecting mirror.
At all times be diligent in cleansing the mirror.
Do not let dust settle on it.
(vide a hymn by Shen Hsiu, d.716)
There is actually no bodhi tree,
Actually no mirror.
Actually there is nothing at all
Where the dust can settle.
(vide Sermons of the Six Patriarchs)
