大毘盧遮那成佛經疏 20.11

20.11

第八名費耗，是除遣義，謂一切業垢等事令無餘也。此尊能除身中一切障，即毘那也迦之類皆令消耗也。其色如聚集眾多電光，不可瞻覩之狀，此是金剛輪同類也。

The eighth is named Consuming (Kṣaya), which has the meaning of dispelling, meaning that all matters such as karmic defilements are eradicated without remainder. This deity can remove all obstacles within the body, completely consuming beings such as the Vināyakas. His color is like a mass of numerous flashes of lightning, appearing dazzling beyond beholding. This is of the same class as the vajracakra.
