Tonight while meditating I was reminded of Xin Shao.

Our body is a Bodhi-Tree,
And our mind a mirror bright.
Carefully we wipe them hour by hour,
And let no dust alight.

And Hui Neng’s response was so brilliant.

There is no Bodhi-tree,
Nor stand of a mirror bright,
Since all is void,
Where can the dust alight.

If you’re interested, these are from the The Sutra of Hui-Neng. I wonder if they describe the difference between Vipassana and Zen. I would like to express the quality of my meditation.

It is raining dust tonight.
Some settles on my mind.
Stillness arises from within
And there is only the breath.
