金光明經文句記 5.237

5.237

初、就天子三義示本。應先了知此金光明是法非譬，以法報應是金光明異名故也。天者，第一義天也。子者，無上眾生本來人也。攬金光明妙三實法為此假人，此人依止第一義天，本離八倒是天護義；此人智光冥法身、金德與法同，為分德義。此人應益，名之為明，義天之力之所加也。

First, pointing out the source with respect to the three meanings of 'Son of Heaven'. One should first clearly know that this 'Suvarṇaprabhāsa' is a dharma, not a metaphor, because the dharma, reward, and response [bodies] are alternate names of Suvarṇaprabhāsa. 'Heaven' means the heaven of ultimate truth. 'Son' means the supreme sentient being, the original person. Gathering the wondrous three real dharmas of the Suvarṇaprabhāsa constitutes this provisional person. This person depends upon the heaven of ultimate truth, fundamentally free from the eight inversions, which is the meaning of 'heavenly protection'. This person's light of wisdom merges with the dharmakāya, and the virtue of gold is identical with the dharma, which is the meaning of 'allotment of virtue'. This person's responsive benefit is named 'splendour', which is that augmented by the power of the heaven of meaning.
