Zen priests write Zen phrases on scrolls or Japanese shikishi papers.
We always feel their works is a deeply connected to Zen.
According to Togami Myodo who is a high priest of Rinzai school, Calligraphy by Zen priests are much difference from professional calligraphers.
It does not matter whether they are better or worse than professionals in the world of Zen.
It is the way of self-expression in Zen.
However I think Zen priests are normally very skilled calligraphers.
