華嚴經探玄記 1.91

1.91

二大本者，如下海雲比丘所受持普眼經，以須彌山聚筆、四大海水墨書一品修多羅，不可窮盡。如是等品復過塵數，此是諸大菩薩陀羅尼力之所受持，亦非貝葉所能書記。

Second, the great recension: As in the case of the Samantamukha Sūtra upheld by the monk Sāgaramegha below, using Mount Sumeru amassed as pens and the waters of the four great oceans as ink, copying a single chapter of the sūtra would still never exhaust it. Such chapters moreover exceed the number of dust motes. This is upheld by the dhāraṇī power of the great bodhisattvas, and it is likewise not something that could be written down on palm leaves.
