法華玄義釋籤 2.66

2.66

理性無體全依無明，無明無體全依法性，理遍一切而無所依，是則名之與體互為因依，名即是體，文字解脫、色為法界等（云云）。

The nature of principle has no independent substance and relies entirely on ignorance; ignorance has no independent substance and relies entirely on dharma-nature. Principle pervades everything and has nothing on which it relies. Thus name and essence serve as mutual cause and reliance: name is itself essence, written words are liberation, form is the dharma realm, and so forth.
