楞伽阿跋多羅寶經註解 4.144

4.144

言一切所作如瓶衣等皆歸無常，則顯如來所修福智皆空無益。若同所作，則一切有作皆應是佛。眾具者，福德莊嚴之具。無差別因性者，謂佛與諸法所作是同，則非別有因性也，故結之云云。

Saying that everything produced, like pots and garments, is impermanent shows that the merits and wisdom cultivated by the Tathāgata would all be empty and unbeneficial. If he were the same as what is produced, then everything produced would have to be a Buddha. 'Provisions' refers to the provisions of merit and adornment. 'No distinct causal nature' means that if the Buddha and all dharmas were the same in being produced, there would be no different causal nature; therefore [the sūtra] concludes in this manner.
