大方廣佛華嚴經隨疏演義鈔 64.41

64.41

疏「龍樹云因緣有二」等者，第二引證略開。即《十二門論》文云「謂水土人工時節穀子為因緣，而芽得生。乳及酵煖人工為緣，而酪得生。泥團輪繩陶師等緣，而器得成。皆外因緣也。」

On the commentary passage "Nāgārjuna says causes and conditions are of two kinds" and so forth: second, citing proof to briefly unfold them. That is, the text of the Dvādaśamukha-śāstra says: "Namely, taking water, earth, human labor, seasons, and grain seeds as causes and conditions, sprouts are able to grow. Taking milk, yeast, warmth, and human labor as conditions, curd is able to form. Through conditions such as lumps of clay, the wheel, string, and the potter, vessels are able to be accomplished. These are all external causes and conditions."
