俱舍論記 24.135

24.135

「論曰至亦名清涼」者，釋初頌。依世俗理，則諸沙門異婆羅門。依勝義理，即前所說真沙門性，經亦說名婆羅門，以能遣除諸煩惱故。與能勤勞息諸煩惱義相似故，故沙門體即婆羅門。即此婆羅門則亦名為梵輪，是真梵王力所轉故。梵所轉輪，故名梵輪。佛與無上梵德相應，是故世尊獨應名梵，由契經說佛名梵等。梵此云淨。

"The treatise states [...] it is also called cool" explains the first verse. In accordance with conventional truth, ascetics are different from brāhmaṇas. In accordance with ultimate truth, the true asceticism spoken of previously is also named 'brāhmaṇa' in the sūtras, because it can expel and eliminate all defilements. Because its meaning is similar to being able to exert effort to quell all defilements, the entity of the ascetic is precisely the brāhmaṇa. This very brāhmaṇa is then also named the wheel of Brahmā (brahma-cakra), because it is turned by the power of the true king Brahmā. It is a wheel turned by Brahmā, and hence named the wheel of Brahmā. The Buddha is associated with unsurpassed Brahmā-virtue; for this reason, the World-Honoured One alone should be named Brahmā, because the sūtras say that the Buddha is named Brahmā and so forth. 'Brahmā' is rendered here as 'pure'.
