One of Rikyu's most well-known sayings is:

"Though many people drink tea,
if you do not know the Way of Tea,
tea will drink you up."

I am sure we will all read this, agree, and continue to remain eons apart in our understanding of what that means. There is a degree of beauty in the strangeness of this encounter with such a simple phrase. One way or another it shows the continuous danger we face while practicing tea.
