俱舍論頌疏論本 29.87

29.87

釋曰：火食一切，豈一念火能燒一切，但約相續說燒一切。佛智亦爾，但據相續名一切智。

The explanation says: When fire consumes everything, how could the fire of a single moment burn everything? It is only with reference to the continuum that it is said to burn everything. The Buddha's wisdom is also like this: it is only in terms of the continuum that he is called omniscient.
