金光明經文句記 4.102

4.102

First, examining the provisional designation. "Due to a single thought of deluded imagination" means: when a male enters the womb, he sees the mother as an object of desire and the father as a rival; he gives rise to greed toward the mother and anger toward the father, and thinking the father's discharge to be his own, he is conceived in the womb by virtue of this deluded thought. For a female it is the opposite. This is detailed in the Great Sūtra. "The beginning of provisional designations" means that the names male and female have their beginning in this deluded thought.
