大方廣佛華嚴經隨疏演義鈔 29.42

29.42

疏「然顯揚第一明三千世界三災所壞」者，即《刊定記》意。上即論文，故如論釋三千。意云：如是三千三災所壞，謂水火風。故知初禪已下即《刊定》取意解釋，謂火災壞初禪、水災壞二禪、風災壞三禪，明知說小千但數初禪。若數中千，即數二禪，以二禪量等中千故。若數大千，即數三禪，三禪量等大千故。是知有百億初禪，有百萬二禪，一千三禪，唯一四禪。然若語量，即是向說，所引文證義則不成，以言三千皆許三災壞故。若中千數於二禪，二禪即火災不壞等，思之。正義如前，引《俱舍》、《正理》已釋。

Regarding the commentary's "However, the Prakaraṇāryaśāsana, fascicle one, clarifies that the trichiliocosm is destroyed by the three calamities": this is the meaning of the Kanding ji. The above is the treatise text, hence explaining the trichiliocosm according to the treatise. The meaning says: such a trichiliocosm is destroyed by the three calamities, namely water, fire, and wind. Thus one knows that below the First Dhyāna is what the Kanding adopted the meaning to explain, holding that the fire calamity destroys the First Dhyāna, the water calamity destroys the Second Dhyāna, and the wind calamity destroys the Third Dhyāna; clearly knowing that speaking of the small thousand-world counts only the First Dhyāna. If counting the medium thousand-world, it counts the Second Dhyāna, because the measure of the Second Dhyāna is equal to the medium thousand-world. If counting the great thousand-world, it counts the Third Dhyāna, because the measure of the Third Dhyāna is equal to the great thousand-world. Thus one knows that there are a hundred kotis of First Dhyānas, one million Second Dhyānas, one thousand Third Dhyānas, and only one Fourth Dhyāna. However, if speaking of measure, that is the aforementioned explanation; the textual proof cited does not establish the meaning, because the text states that the trichiliocosm is entirely admitted to be destroyed by the three calamities. If the medium thousand-world counts the Second Dhyāna, the Second Dhyāna would not be destroyed by the fire calamity, and so forth; contemplate this. The correct doctrine is as before, already explained by citing the Kośa and the Nyāyānusāra.
