礼记射义

射者，进退周还必中礼。内志正，外体直，然后持弓矢审固。持弓矢审固，然后可以言中。此可以观德行矣。

射者，仁之道也。射求正诸己。己正而后发，发而不中则不怨胜己者，反求诸己而已矣。

日文

射は進退周還必ず札に中り、内志正しく、外体直くして、然る後に弓矢を持ること審固なり。弓矢を持ること審固にして、然る後に以って中ると言うべし。これ以って徳行を観るべし。

射は仁の道なり。射は正しきを己に求む。己正しく而して後発す。発して中らざるときは、則ち己に勝つ者を怨みず。反ってこれを己に求むるのみ。

English

The shooting, with the round of moving forward or backward can never be without courtesy and propriety (Rei). After having acquired the right inner intention and correctness in the outward appearance, the bow and arrow can be handled resolutely. To shoot in this way is to perform the shooting with success, and through this shooting virtue will be evident.

Kyudo is the way of perfect virtue. In the shooting, one must search for rightness in oneself. With the rightness of self, shooting can be realized. At the time when shooting fails, there should be no resentment towards those who win. On the contrary, this is an occasion to search for oneself.
