景云：此七門內，初三門通分別三性，後四門唯分別遍計所執性。三性之義古來大德種種解釋，乃有多塗。且如奘法師出三性義章，最明為好，彼立三性以三門分別。一、情事理門；二、塵識理門；三、染淨通門。

Jing says: Within these seven gates, the first three gates apply generally to distinguishing the three natures, while the latter four gates exclusively distinguish the parikalpita nature. The meaning of the three natures has been variously explained by past masters through many approaches. For instance, Master Xuanzang set forth an essay on the meaning of the three natures, which is the clearest and best. He established the three natures by distinguishing them through three gates: first, the gate of sentiment, fact, and principle; second, the gate of sensory dust, consciousness, and principle; third, the gate of defilement, purity, and commonality.
