俱舍論疏 1.194

1.194

論「顯立名因至故名無表」，此第五釋無表名也。頌文略故，但言「由此」。《成業論》云「何故名表？此能表示自發業心令他知故。頌文云『外發身語業，表內心所思，譬如潛淵魚，鼓波而自表。』頌言由此者，為顯由無此表義故名為無表。」

The Śāstra says: "Showing the reason for establishing the name... hence it is called unmanifest." This is the fifth section, which explains the name 'unmanifest.' Because the verse text is concise, it merely says: "From this." The *Karmasiddhiprakaraṇa* says: "Why is it called 'manifest'? It can indicate the mind initiating its own action and make it known to others. The verse says: 'Outwardly it initiates bodily and vocal actions, / manifesting what is thought by the inner mind; / just as a fish hidden in a deep pool / stirs waves and thereby manifests itself.' The verse says 'from this' to show that, because of the lack of this meaning of manifest, it is called 'unmanifest.'"
