首楞嚴義疏注經 2.347

2.347

婆羅門，此云梵志，或淨志。投灰等，即苦行外道，裸形披髮，鞭纏棘刺，五熱炙身也。我遍十方者，此外道不知阿賴耶識為界趣生本，含藏種子，惑潤受生，遂計身中有一神我常在不滅，處處受生遍十方界。彼之所說計我行相，似濫真覺，故云有何差別。

Brāhmaṇa is translated here as "one of pure will" (brahmacārin) or "pure intention." "Ash-smearers and so forth" are the ascetic heterodox practitioners who go naked with dishevelled hair, whip themselves, entangle themselves in thorns, and scorch their bodies with the five fires. Regarding the "self pervading the ten directions," these heterodox practitioners do not know that the ālayavijñāna is the root of the realms and destinies, containing the seeds, and that being moistened by defilement it undergoes rebirth; thus they imagine that within the body there is a spiritual self that permanently exists without perishing, undergoing rebirth in various places and pervading the realms of the ten directions. The active characteristics of their conceptualized self seem to be confounded with true enlightenment, hence he asks, "what difference is there?"
