4.154

"Future..." below: concludes the formation of the doubt. The meaning is: since both cause and fruit are without marks, cause and fruit are both profound. Only one such as I, receiving it in person, can comprehend it; how could dull-rooted beings in the final age believe and accept it? Since they will not believe and accept it, what benefit is there in speaking it in vain? Presenting the doubt, the inquiry of the sūtra means: will there be sentient beings in the future final age who, hearing these passages and phrases profound in both cause and fruit, give rise to true faith? "Could there be" (頗) means "capable of." The intent is to distinguish it from superficial faith, hence it says "true faith."
