妙法蓮華經文句 4.48

4.48

經無文，義推應爾。引三歸一，三望一，一則是當；舉事為譬，譬即是現。準後望前，應如所問。

The sūtra has no explicit text, but deduced by principle it should be so. Bringing the three to converge into the one: viewing the one from the perspective of the three, the one is the future; citing an event as a parable, the parable is the present. Looking from the latter to the former, it should be as you have asked.
