因明入正理論疏 3.29

3.29

問：「既於德、業一一皆有，云何不言有一德、業？」答：「實有多類，不言有一；但言有實，即犯不定，謂子微等皆有實故。德、業無簡，不須一言。」

Question: 'Since it possesses each quality and action individually, why does he not say "possessing one quality and action"?' Answer: 'Substance has many classes; if he did not say "one" and merely said "possessing substance", he would commit the fault of being inconclusive, for daughter atoms and so forth all possess substance. Quality and action require no qualification, so the word "one" is not needed.'
