1.221

「於此經中至名現在」者，三世門。正滅是現在故。舉已滅名過去，簡異擇滅。非擇滅故，言無常已滅。已生是現在。若未來未至已生位名未來，至已生位未落謝過去名現在。《集異門》同此論。

"In this sūtra ... is called the present": the gate of the three times. That which is right at the point of perishing is the present; hence presenting what has already perished is called the past, to distinguish it from analytical cessation. Because it is not non-analytical cessation, it says "impermanently already perished". What has already arisen is the present. If in the future it has not yet reached the state of having already arisen, it is called the future; when it reaches the state of having arisen and has not yet fallen into the past, it is called the present. The *Saṅgītiparyāya* agrees with this treatise.
