摩訶止觀 5.136

5.136

止秖是智；智秖是止。不動止秖是不動智；不動智秖是不動止。不動智照於法性，即是觀智得安，亦是止安；不動於法性相應，即是止安，亦是觀安，無二無別。

Calming is simply wisdom; wisdom is simply calming. Unmoving calming is simply unmoving wisdom; unmoving wisdom is simply unmoving calming. When unmoving wisdom illuminates dharmatā, this is contemplative wisdom attaining stability, which is also the stability of calming; when one is unmoved and resonates with dharmatā, this is the stability of calming, which is also the stability of contemplation, without duality or distinction.
