法華玄義釋籤 17.10

17.10

義有傍正，正顯體已復順此三。若爾即是用所依體，體能成用，亦宗所顯體，體能成宗，故以三譬，復對三法。

The meanings have secondary and primary aspects: after primarily revealing the substance, one then accords with these three. If so, then it is the substance upon which function relies, and substance is able to establish function; it is also the substance revealed by the lineage, and substance is able to establish the lineage. Therefore, using the three similes, one further corresponds them to the three dharmas.
