11.46

釋曰：唯六欲天受妙欲境，於中初二依地居天，形交成婬，與人無別，然風氣泄熱惱便除，非如人間有餘不淨。夜摩天眾纔抱成婬。都史多天但由執手。樂變化天唯相向笑。他化自在天相視成婬。隨彼諸天男女膝上有童男童女欻然化生，即說為彼天所生男女也。

Explanation: Only the six gods of the desire realm experience exquisite sensory objects of desire. Among them, the first two, relying on terrestrial dwelling, accomplish sexual union through physical intercourse, no different from humans; however, as the wind-element is discharged, their feverish torment is removed, unlike the remaining impurities of the human realm. The hosts of the Yāma gods accomplish sexual union merely by embracing. The Tuṣita gods do so simply by holding hands. The Nirmāṇarati gods merely smile toward each other. The Paranirmitavaśavartin gods accomplish sexual union by gazing at each other. Upon the laps of those gods, male or female, a young boy or young girl is suddenly born by transformation, which is then spoken of as the son or daughter born to those gods.
