Oryoki (The Practice of the Soto Zen Eating Bowl) Instructions for the Tenzo by Dogen

Long interesting post. Skip (way) down to "Tenzo kyokun:
Instructions for the Tenzo," where we find:

I asked, 'What are words?'

The tenzo said, 'One, two, three, four, five.'

I asked again, 'What is practice?'

'Everywhere, nothing is hidden.'
