佛頂尊勝陀羅尼經教跡義記 2.31

2.31

唐言舒遍也。解曰：唵字加持已，淨除二障煩惱所知，神力光明照曜舒遍，根本後得緣俗緣真，六趣稠林一切皆照。只為有情業重不遇真言，流浪三途不聞斯句，因麁果重出路無由，若得真言阿闍梨教，照曜舒遍，必淨苦源。又解：舒遍者，以此陀羅尼光無有障礙，觸斯光者皆得淨除。若有先亡所在之處淨土一把，誦此真言二十一遍，散其亡者人身骨之體，即得離苦。具如下疏文解。平等照曜染淨不差，名言性空空何可得？照曜光發愚冥皆除，剎土現身所作無滯。

In Chinese it means "diffusing and pervading." Explanation: Having been empowered by the syllable OṂ, one purifies the two obstacles—afflictive and cognitive; the light of supernormal power shines and diffuses everywhere, fundamental and subsequently attained [cognition], taking the conventional as object and taking the ultimate as object, illuminating the dense forest of the six destinies without exception. Only because the karma of sentient beings is heavy do they fail to encounter the mantra, wandering adrift in the three evil paths without hearing these phrases; with coarse causes and heavy fruits, they have no way to escape. If they obtain the teachings of a mantra ācārya, shining and diffusing pervasively, they will certainly purify the source of suffering. Another explanation: As for diffusing and pervading: because the light of this dhāraṇī has no obstruction, all who touch this light are purified. If at the place where a deceased person lies, one takes a handful of clean earth, recites this mantra twenty-one times, and scatters it over the corpse and bones of that deceased person, they will immediately be freed from suffering. The details are as explained in the commentary below. Shining equally, defilement and purity are no different; the nature of names and words is empty—how could emptiness be grasped? When the shining light radiates, foolish darkness is entirely dispelled; manifesting bodies in the lands, their activities are unobstructed.
