瑜伽論記 5.338

5.338

未來無相，故無分別者，釋頌未來無有相，謂說未來相，都無有都無分別，而生雜染。

Regarding "the future has no characteristic, and therefore there is no conceptual construction": this explains the verse's "the future has no characteristic." It means that in explaining the future characteristics, they are entirely nonexistent and entirely without conceptual construction, [such that] they could give rise to defilement.
