俱舍論疏 6.58

6.58

論「豈不現見至亦為因果」，有部答也。豈不現見燈焰與明為因、芽與影為因。雖是同時，有因果義。因何得說不見如是同時因果？

On the Śāstra's statement: "Is it not visibly observed... also constitute cause and effect?": this is the Sarvāstivādin's reply. Is it not visibly observed that the flame of a lamp serves as the cause for illumination, and a sprout serves as the cause for a shadow? Although they are simultaneous, they have the meaning of cause and effect. How can you say that such simultaneous cause and effect is not seen?
