1.336

法無形相如虛空故　肇曰。萬法萬形萬形萬相。解曰。此明一法萬形無定形故無形。亦一體多相無定相故無相。

"'The Dharma is without form or mark, because it is like empty space.'" [Seng]zhao said: "The ten thousand dharmas have ten thousand forms, and ten thousand forms have ten thousand marks." The explanation says: "This clarifies that a single dharma has ten thousand forms and no fixed form, hence it is 'without form'; also, a single essence has many marks and no fixed mark, hence it is 'without mark.'"
