釋曰：三十三天由自通力，能從本處昇夜摩天。或復依他，謂得通者及上天者接往夜摩天。所餘諸天昇上例爾，若來若至，下見上天。然下眼不能覩上界地，非境界故，如不覺彼觸，因此義便，復明天量。有餘師說：「夜摩等四依處量同妙高山頂。」有餘師說：「上倍倍增。」有餘師說：「初靜慮量等一四大洲，第二靜慮等小千界，第三靜慮等中千界，第四靜慮等大千界。」

Explanation: The Trāyastriṃśa gods, by their own supernormal power, are able to ascend from their native place to the Yāma heaven; or else relying on others, meaning that those who have obtained supernormal powers and higher gods escort them to the Yāma heaven. The remaining gods ascending above are analogous to this: whether coming or arriving, those below see the higher gods. However, the lower eye cannot view the realm and ground of the higher, because it is not its domain, just as one does not perceive their touch. Taking advantage of this topic, the sizes of the heavens are explained again. Other masters say: 'The receptacles of the four [heavens] beginning with Yāma have the same measure as the summit of Mount Sumeru.' Other masters say: 'Above, they double successively.' Other masters say: 'The measure of the first dhyāna is equal to one set of the four great continents; the second dhyāna is equal to a small-thousandworld; the third dhyāna is equal to a medium-thousandworld; the fourth dhyāna is equal to a great-thousandworld.'
