四分律行事鈔資持記 2.238

2.238

答中，初正示。如下，喻顯。城池弓刀喻受體，擬捍擊賊喻隨行。下指《戒疏》。文亦出《業疏》，疏云：戒實能防遮斷不起，常須隨行策持臨抗，方遊塵境不為陵侵；如世弓刀，深能御敵；終須執持，刀陷前陣。

In the answer, first he shows it directly. From 'Just as' downward, he illustrates it with an analogy. The city moat, bow, and sword illustrate the reception-essence; drawing back [the bow] to defend and strike the bandits illustrates subsequent practice. Below, he refers to the Precept Commentary. The text also appears in the Karma Commentary, which states: 'The precepts can truly defend, stop, and cut off [faults] so they do not arise; one must constantly rely on subsequent practice to encourage, uphold, confront, and resist, and only then when wandering through sensory objects will one not be encroached upon. Just as in the world bows and swords are deeply capable of warding off enemies, one must after all hold and wield them for the blade to plunge into the opposing ranks.'
