瑜伽師地論略纂 11.60

11.60

論云「鄔波尼殺曇分」者，此數之極也，不可翻名。又云：如大乘經有六百大數，有《華嚴經》有百二十大數，有《俱舍論》有六十數，此別立也。

Regarding the treatise's mention of "the upaniṣad-fraction": this is the ultimate limit of enumeration, an untranslatable term. It also says: just as Mahāyāna sūtras have six hundred great numbers, the Avataṃsaka Sūtra has one hundred and twenty great numbers, and the Abhidharmakośa-bhāṣya has sixty numbers, this is established separately.
