金光明經文句記 1.107

1.107

二、觀行釋。若《妙經疏》先以三字對於五陰，次觀三字而為三德，達陰即理也。今此文略，直以三字表示三德，雖不云陰，義當體陰而為三德。須知陰是見思報法，此乃修惡即是性惡而為三德。其善惡王若非性具，何能常住祕藏之處？心數塵勞若非性惡，何由能得同入其中？

Second, the interpretation in terms of contemplative practice. If according to the Commentary on the Wonderful Sūtra, it first matches the three characters against the five skandhas, and next contemplates the three characters as the three virtues, comprehending that the skandhas are principle itself. The present text is brief and directly uses the three characters to indicate the three virtues; although it does not speak of the skandhas, its meaning corresponds to realizing that the skandhas are themselves the three virtues. One must know that the skandhas are the retributive phenomena of [delusions of] views and thoughts; here, cultivated evil is itself inherent evil, constituting the three virtues. If their king of wholesome and unwholesome were not inherently possessed, how could it constantly abide in the secret treasury? If the mental factors and dust-like defilements were not inherent evil, how could they enter together into it?
