I've been reading a great little book called Zen Bow, Zen Arrow: The Life and Teachings of Awa Kenzo
Kenzo called his new system Daishado-kyo, “the Great Shooting Way Teaching.” Here is an out-line of the principles of Kenzo’s Great Shooting Way Teaching:
Trust in the practice of the Way of the Bow. Archery is not an art, it is a Way. When you practice the Way, it is not just training in technique; it is spiritual forging. Forging your spirit is to become empty, and to focus on your center. To become empty is to become one with the divine—this is the Way. To attain the Way is to manifest the Way. The Way of the Bow is to manifest your self Buddha-nature and arrive at the ultimate.
