答：所成之法雖不離本，要本轉變方堪用之，故言受用所成之法；如所成器雖體即金，要成其器方可受用，故言用器不說用金，此亦應爾。

Answer: Although the produced phenomena are not separate from the root, the root must undergo transformation before it is suitable for use; therefore, it speaks of experiencing the produced phenomena. Just as an utensil that is produced, though its substance is gold, can only be used once it has formed the utensil—hence one speaks of using the utensil, not of using the gold—this should also be like that.
