瑜伽論記 2.85

2.85

This text specifically says that the Yāma heaven is named 'playful negligence' and the Tuṣita heaven is named 'mutual wrath', and next it individually clarifies the gods who delight in transformations and the gods who control transformations made by others. Master Xuanzang explained: in order to graduate the four heavens dwelling in the sky, it made this statement; because the heaven of controlling transformations made by others belongs exclusively to the sixth, and the heaven of delighting in transformations belongs exclusively to the fifth, it therefore says that mutual wrath belongs to the fourth heaven and playful negligence belongs to the third heaven. In principle, playful negligence and mutual wrath apply to all four heavens dwelling in the sky; because the two heavens dwelling on the ground engage in sexual desire similarly to humans, they are not called 'pure already-born'. The four heavens dwelling in the sky merely embrace, hold hands, smile at each other, or look at each other, and their sexual acts are slight; therefore they receive the name 'pure already-born'. Based on that Dazhidulun, negligence and wrath both apply to the six desire heavens. In the dual-category case, regarding 'sentient beings abiding in the stage of already-born, etc.': even if they do not abide in the stage of the kalala, when reaching the stage of the already-born, moisture-born, apparitional, and so forth are all of this category.
