四分律刪繁補闕行事鈔 1.56

1.56

又所引部類，必取義勢相關者，可用證成；必緩急重輕，是非條別者，準論不取。故文列四說，令勘得失。《十誦》墨印，義亦同之。若此以明，則心境相照，動合規猷；繁略取中，理何晦沒。若不鏡覽諸部，偏執一隅，涉事事則不周，挍文文無可據；遂師心臆見，各競是非，互指為迷，誠由無教。

Moreover, as for the schools cited, one must take those whose drift of meaning is relevant, which can then be used to corroborate and establish [the point]. If the laxity and strictness, lightness and heaviness, or right and wrong are distinctly divergent, in accordance with the treatises, they should not be adopted. Therefore, the text sets forth four types of explanations so as to examine gains and losses. The "ink-seal" in the Daśādhyāya-vinaya has the same meaning. If illuminated in this manner, mind and circumstance will reflect one another, and every movement will accord with the proper norms. Taking the middle path between excess and brevity, how could the principle ever be obscured? If one does not mirror and survey the various schools and instead obstinately clings to one corner, in undertaking affairs the affairs will not be comprehensive, and in collating texts there will be no evidence to rely on; one then follows one's own mind and subjective views, contending over right and wrong, and pointing to each other as misguided—this truly stems from lacking authoritative teaching.
