三、法同法性。「一法入一切法」等者，荊溪云：既云諸法悉有安樂，即是本有義。云相入，既本相在，更云互入者，示相攝相，令知相在。「通達法性」者，法雖本同，必須實慧而遍入之，方了諸法互入之性。又法即智慧，以境智不二故。理智合者，一多相入，垂應自在也。

Third, the Dharma is identical with the Dharma-nature. Regarding "one dharma enters all dharmas" and so forth: Jingxi says: Since it says that all dharmas possess peaceful joy, this is the meaning of fundamental existence. Speaking of mutual entering: since they fundamentally abide in each other, further speaking of mutual entering demonstrates mutual containment, causing one to know that they abide in each other. Regarding "penetrating the Dharma-nature": although dharmas are fundamentally identical, one must use real wisdom to universally enter them, and only then comprehend the nature of mutual entering of all dharmas. Furthermore, the Dharma is precisely wisdom, because object and wisdom are non-dual. When principle and wisdom unite, the one and the many mutually enter, and response body manifestations are at ease.
