說無垢稱經疏 2.114

2.114

贊曰：此下第二佛現神力。於中有三：一變多為少、二變小為大、三彰現其中。此有二文：一、變多為少，合成一蓋，表修四無量等種種妙因，同證一真法界故。二、變小為大，䨱三千界故，顯真如理遍充法界無不在故，亦顯無量䨱一切故，又顯因小而果大故。千四天下有一輪圍，名小千界。千小千界有一輪圍，名中千界。千中千界有一輪圍，故名三千大千世界。第三重千，故云大千。由此下言輪圍山、大輪圍山。

Commentary: Below this is the second: the Buddha displaying spiritual power. Within it there are three [aspects]: first, transforming the many into the few; second, transforming the small into the large; third, manifesting [everything] within it. This passage has two: First, transforming the many into the few, combining them into one parasol, which signifies cultivating various wondrous causes such as the four immeasurables to jointly realize the single, true dharmadhātu. Second, transforming the small into the large, covering the trichiliocosm, which reveals that the principle of tathatā completely pervades the dharmadhātu without being absent anywhere, also manifests that the immeasurables cover everything, and further manifests that the cause is small while the fruit is vast. A thousand four-continents have one encircle mountain ring, called a small chiliocosm. A thousand small chiliocosms have one encircle mountain ring, called a medium chiliocosm. A thousand medium chiliocosms have one encircle mountain ring, and is therefore called a great trichiliocosm. It is the third tier of thousands, so it is called 'great chiliocosm.' Hence below it speaks of the Cakravāḍa mountains and the Mahācakravāḍa mountains.
