瑜伽論記 2.206

2.206

第二他返詰中，如說：一切有，謂十二處者，言意顯十二處通三世，意識所緣法境，三世俱是有，若去來無便違此教。

In the second part, the other's counter-question, as stated: "All exists refers to the twelve āyatanas": this means showing that the twelve āyatanas span the three times, and the mental consciousness's cognitive object, the objective realm of dharmas, exists across all three times; if past and future were non-existent, it would contradict this scripture.
