摩訶止觀 3.147

3.147

雖不可說，有四悉檀因緣故，亦可得說。或說自生境智，乃至或說無因境智。雖作四說，性執久破，如前。但有名字，名字無性，無性之字是字不住，亦不不住，是為不可思議。故《金光明》云：「不可思議智境，不可思議智照。」即此意也。

Although it is ineffable, because of the conditions of the four siddhāntas, it can also be spoken. One may speak of a self-arisen realm and wisdom, up to speaking of a causeless realm and wisdom. Although one delivers the four expositions, grasping at inherent nature has long been broken, as before. There are only names, and names have no inherent nature; words without inherent nature neither abide nor do not abide—this is the inconceivable. Therefore the Suvarṇaprabhāsa states: "The inconceivable wisdom-realm, the inconceivable wisdom-illumination." This is precisely the meaning.
