金光明經文句記 2.179

2.179

二、從修有則別。不分修性即一、三不互融則異，別異故縱、並一故橫，是則乖於所詮法體；若能妙達秪一法性，而能成就一性二修，名即一而三也。修性而成，而其三身一性本具，名即三而一也。此乃得云全性成修、全修在性，性無所移、修常宛爾，方合能詮玄妙之文矣。

Second, existing through cultivation, they are distinct. If one does not distinguish cultivation and nature, they are identical; if the three do not mutually integrate, they are different. Because of being distinct and different, they are vertical; because of being aligned as one, they are horizontal. This would then conflict with the substance of the dharma that is explained. If one can wonderfully realize that it is only a single dharma-nature, yet it can accomplish one nature and two cultivations, this is called being three while identical to one. Accomplished through cultivation and nature, these three bodies are originally inherent in the single nature, which is called being one while identical to three. This can then be described as: the entirety of nature becomes cultivation, and the entirety of cultivation exists in nature; nature undergoes no change, yet cultivation is ever distinct. Only then does it accord with the profound and wonderful text that expresses it.
