首楞嚴義疏注經 6.70

6.70

「若有眾生不壞男根，我於彼前現童男身而為說法，令其成就。若有處女愛樂處身，不求侵暴，我於彼前現童女身而為說法，令其成就。」

"If there are living beings who do not destroy their male faculty, I appear before them in the body of a maiden boy and expound the Dharma for them, causing them to achieve [their wish]. If there are virgins who delight in maintaining maidenhood and seek no violation or ravishment, I appear before them in the body of a maiden girl and expound the Dharma for them, causing them to achieve [their wish]."
