唯識二十論述記 2.89

2.89

述曰：下破薩婆多無方分義，釋頌第三句中初「無」字。此敘彼計。彼由極微極微、圓故，能對之東，亦非是東，餘方亦爾，無異方分，以極微細，其相圓故。

Commentary: Below is the refutation of the Sarvāstivāda position on having no spatial divisions, explaining the first word "no" in the third line of the verse. This recounts their position: according to them, because paramāṇus are extremely minute and spherical, the east faced [by one] is not east, and the other directions are likewise; they have no different spatial divisions because they are extremely minute and spherical in characteristic.
