金光明經文句記 2.336

2.336

二、「天紺」下，寶間表境，二：初、直表三諦；二、「一地」下，兼表融即。室中一地有此三相，可表妙境三一相即。行者應知，諦智名別其體不殊，欲彰修證彊立能所。

Second, from "heavenly dark-blue" down, the interspersed jewels represent the objects of contemplation, with two [parts]: first, directly representing the three truths; second, from "one ground" down, concurrently representing harmonization and identity. The single ground in the room having these three characteristics can represent the mutual identity of the three and the one of the subtle object. The practitioner should know that truth and wisdom differ in name but their substance is not distinct; wishing to make evident cultivation and realization, subject and object are arbitrarily posited.
