法華玄義釋籤 4.41

4.41

次二妙妙上三法者，欲明三妙在於《法華》方得稱妙，故須二妙以妙三法，故諸味中雖有圓融、全無二妙，三被妙已故三即妙，故上文云「此妙即法，此法即妙，故得三法皆具於十，成三十妙」，良由於此。

Next, regarding the two kinds of marvelousness making the aforementioned three dharmas marvelous: in wishing to clarify that the three kinds of marvelousness can only be termed marvelous in the Lotus Sūtra, it is necessary to employ the two kinds of marvelousness to make the three dharmas marvelous. Therefore, although there is perfect fusion among the various flavors, there is completely lacking the two kinds of marvelousness. Once the three have been made marvelous, the three are themselves marvelous. Hence the earlier text says, “This marvelous is precisely the Dharma, and this Dharma is precisely the marvelous; therefore the three dharmas each possess the ten, completing the thirty marvelousnesses.” It is truly due to this.
