俱舍論疏 1.203

1.203

論「長謂增盛或復流引」，此逐難釋。增盛者，如長小成大，體增盛也。流引者，謂轉至餘方，如水流等，體不增也。

The Śāstra says: "'Growth' means increase, or else moving along." This explains following objections. 'Increase' is like growing from small to large, with the substance increasing. 'Moving along' means shifting to another location, like flowing water, where the substance does not increase.
