三、明方便解脫者，此經云「有慧方便解」，即是方便解脫也。祇是實慧分別，則行於非道，通達佛道；住不思議解脫，種種變現，大用無方，物所不測；和光利物，而不同塵；自既無縛，能解他縛，故名不思議方便解脫也。

Third, explaining the liberation of skillful means: this sūtra says, 'There is liberation through skillful means with wisdom'—this is liberation of skillful means. This is merely real wisdom discriminating, thereby practicing in non-ways while penetrating the Buddha way; abiding in inconceivable liberation, manifesting all manner of transformations, its great function boundlessly vast, beyond what beings can fathom; blending its light and benefiting beings without becoming identical with the dust; being oneself unbound, one can untie the bonds of others. Hence it is called the inconceivable liberation of skillful means.
