5.115

四、具緣者，具四緣成犯：一、性非闇鈍，二、惰不習學，三、隱愚詐智，四、為師授戒。故以為犯。

Fourth, regarding the fulfillment of conditions: fulfilling four conditions constitutes an offense: 1. One's nature is not dull and dim; 2. One is indolent and does not study; 3. One conceals foolishness and feigns wisdom; 4. One acts as a master conferring precepts. Hence it constitutes an offense.
