金剛三昧經論 2.105

2.105

論曰：此下重遣疑情，三番問答次第遣疑。此初番者，問依喻疑，答就法遣。答意而言：經五十年，喻於一念心動。十方遊歷，喻於遠行遍計。斯則一念之頃遍計諸法，即於此念其父告言，告言之時即得醒悟，念究竟時得無所得。如覺金錢而無所得，所以父告非為經久，但為顯一念具五十惡，故喻中說經五十年耳。答意如是。是義云何？謂由無明力而起四相，四相無明和合力故，能動一心生住異滅。一心既動帶此四相，是故說名一念心動。如《起信論》云「自性清淨心，因無明風動」，乃至廣說。於中委悉，如彼記說。

The treatise states: From this point downward, doubts are repeatedly eliminated through three rounds of questions and answers, eliminating doubts in sequence. In this first round, the question doubts based on the parable, and the answer eliminates [the doubt] in terms of the principle. The import of the answer is: 'fifty years' is an analogy for the stirring of the mind in a single thought; 'wandering the ten directions' is an analogy for the far-reaching travel of pervasive conceptualization. Thus, in the instant of a single thought, one pervasively conceptualizes all phenomena; right in this thought the father tells him, and at the time he is told, he immediately attains awakening; when the thought reaches its consummation, he attains non-attainment. Just as awakening to the gold coins involves no attainment, so the father's telling is not after a long time; it is merely to reveal that a single thought contains the fifty evils that the parable speaks of 'fifty years'. Such is the import of the answer. What does this mean? It means that through the power of fundamental ignorance, the four characteristics arise; through the combined power of the four characteristics and ignorance, they are able to stir the one mind into arising, abiding, changing, and ceasing. Once the one mind is stirred, it bears these four characteristics, and therefore it is called 'the stirring of the mind in a single thought'. As the Treatise on the Awakening of Faith states: 'The intrinsically pure mind is stirred by the wind of ignorance,' and so on, up to the detailed explanation. The particulars therein are as explained in that commentary.
