首楞嚴義疏注經 5.368

5.368

「佛問圓通，我以諦觀身、界二塵等無差別，本如來藏虛妄發塵，塵銷智圓，成無上道，斯為第一。」

"The Buddha asked about perfect penetration. By closely contemplating the two dusts of body and realm as equal and without difference—fundamentally the tathāgatagarbha falsely giving rise to dust, and with dust eliminated, wisdom becoming perfect, thereby achieving the unsurpassed Way—this is foremost."
