St Paul coming down as Shenxiu in China

The body is a Bodhi tree,
the mind a standing mirror bright.
At all times polish it diligently,
and let no dust alight.

When the disciples saw this gatha on the wall, there was a great stir. When Hongren saw it, he told them, "Practice according to this gatha, you will not fall into the evil realms, and you will receive great benefits. Light incense and pay respect to this gatha, recite it and you will see your essential nature." All the disciples praised and memorized the gatha.
