論。云何為二至心生滅門　述曰。此列二門也。即體絕相名真如門。隨緣變動名生滅門。體雖無別而義有異。約義異故。故說為門。

[Treatise:] What are the two? […] the mind in terms of arising and ceasing. [Exposition:] This lists the two aspects. That which is identical with the essence and transcends characteristics is called the aspect of suchness. That which accords with conditions and transforms in motion is called the aspect of arising and ceasing. Although the essence has no distinction, the meanings differ; because of the difference in meaning, they are spoken of as "aspects."
