問：如箭射空去時用力可言有因，墮不用力誰為其因，彼即通言箭去之時為楯等障即便墮落，設無物障用力射時即墮因，若本不射今何由墮，由此道理，法生滅皆悉有因故，今牒彼毘曇義來正破，不應謂生因即是滅因其相異故，生滅既殊，云何因一？

Question: Just as when an arrow is shot into the air, when it goes forward effort is applied and one may say there is a cause; when it falls without effort being applied, what is its cause? They then resolve it by saying: When the arrow travels, it is obstructed by a shield or the like and immediately falls; even if there is no object obstructing it, the effort applied when shooting is precisely the cause of falling; if one had not shot originally, by what reason would it now fall? By this principle, both the arising and cessation of phenomena all have causes. Therefore, now citing that Abhidharma doctrine to refute it directly: it should not be said that the cause of arising is precisely the cause of cessation, because their characteristics are different. Since arising and cessation are distinct, how could the cause be one?
