大方廣佛華嚴經疏 41.19

41.19

第三初中後際皆悉平等者，即數差別無生，於三時中染淨法不增減故。謂先際非染增淨減、後際非淨增染減、中際亦非半增半減，以知三際皆空無自性故。然準《瑜伽》，前三句約三世，此中約位以明三際，故論就染淨明之。

Third, "the initial, middle, and final limits are all completely equal" is the non-arising of numerical distinction, because defiled and pure dharmas neither increase nor decrease across the three times. That is, the initial limit is not defilement increasing and purity decreasing; the final limit is not purity increasing and defilement decreasing; and the middle limit is also not half increasing and half decreasing, because one knows that the three limits are all empty and devoid of self-nature. However, following the *Yogācārabhūmi*, the former three phrases are explained in terms of the three periods of time, whereas here the three limits are explained in terms of stages; therefore the commentary explains them in terms of defilement and purity.
