金光明經文句記 2.304

2.304

二、「即是」下，正明施相。文略不語。三教菩薩、別教六度可為餘食，髓是中道必在己身，是故餘髓但在真諦。

Second, from "that is" down, directly explaining the characteristics of giving. The text is brief and does not say [more]. The bodhisattvas of the three teachings and the six perfections of the separate teaching can serve as the "other food"; marrow is the Middle Way and must reside in one's own body; therefore, other marrow lies only in the ultimate truth (*paramārtha-satya*).
