匱正法（上狂位反匱匣也從匚貴聲或作櫃經云匱法匱者慳法法入身心祕之不說慳惜聖教不肯流傳藏而祕之猶如匱匣名為匱法佛說此人其罪甚重寧造無間不作匱法）。

匱正法 (The upper character is pronounced 狂 + 位 fanqie. A 匱 is a box; it derives from 匚 with 貴 as phonetic, or is written as 櫃. The sūtra speaks of 'holding back (stashing away) the Dharma' (匱法). 匱 means to be stingy with the Dharma: when the Dharma enters one's body and mind, one secretes it and does not preach it, miserly with the sacred teachings, unwilling to circulate and transmit them, keeping them hidden and concealed just like putting them in a chest; this is called 'holding back the Dharma'. The Buddha taught that this person's sin is extremely heavy: better to commit the uninterrupted [hell deeds] than to hold back the Dharma).
