89.16

疏十四「瑟吒字」，後「普光明」下，會經。《智論》單云「吒」字。論云「若聞吒字，即知一切法無障礙相，以吒婆此言障礙故。」釋曰：障礙即制伏任持。

Regarding the commentary's "Fourteen: the syllable ṣṭa": afterwards, from "universal radiance" down, it reconciles with the sūtra. The Dazhidulun simply has the syllable ṭa. The treatise says: "Hearing the syllable ṭa, one immediately knows that all phenomena have no mark of obstruction, because here ṭambha means obstruction." Explanation: Obstruction means subduing and maintaining.
