仁王護國般若經疏 1.17

1.17

問：宗與體何異？答：宗如綱裘，體如毛目。振裘毛舉、動綱目起，宗體之義若此。又如釵釧，金銀是體，匠者造之是宗。今實相之理是體，修因得果為宗也云云。

Question: How do the gist and the substance differ?
Answer: The gist is like the headrope [of a net] or the collar [of a robe]; the substance is like the meshes or the fur. Shake the collar and the fur rises; pull the headrope and the meshes open—such is the meaning of the gist and the substance. Again, it is like hairpins and bracelets: gold and silver are the substance, and the craftsman fashioning them is the gist. Here, the principle of dharmatā is the substance, and cultivating the cause to attain the fruit is the gist, and so forth.
