"The ikebana, the cut of the flower could only have been made by a master swordsmen."
Wonderful. I have also found that the greatest teachers tend to show their brilliance in almost invisible details, easy to miss for those who don't look without prejudice.
For example, I am reminded of Isoyama sensei. Have you seen him sit in seiza? It is a beautiful sight. When you see this, you know that he has a lot to teach.
