瑜伽論記 18.133

18.133

若於當來我無變者，應無生老病死及五道輪轉，何故汝等外道宗中每自說。言我於未來當受生死五道輪迴，於現法中我若不變，便應於彼愛非愛等種種境界，應無苦樂及貪瞋等種種煩惱，云何現在逢違順等緣，言我受苦或時受樂生貪瞋等，既為緣變云何是常。

If the self did not change in the future, there should be no birth, old age, sickness, death, and transmigration through the five destinies; why do your non-Buddhist schools constantly profess: "I shall undergo transmigration through birth and death in the five destinies in the future"? If the self did not change in the present lifetime, then with respect to various pleasant and unpleasant sensory objects, there should be no suffering, pleasure, or various afflictions such as greed and anger. Why is it that, when encountering adverse and favorable conditions in the present, you say: "I experience suffering" or at times "experience pleasure", giving rise to greed, anger, and so forth? Since it changes on account of conditions, how could it be permanent?
