2.3

釋曰：一有見謂色者，十八界中，一界有見，所謂色界。由顯形色在此在彼差別不同，遂能示現此彼言說，言說名見。有彼言說故，故名有見。亦解：見謂眼根觀照色故，色有眼見，名為有見。

Commentary: 'One is visible, namely form' means that among the eighteen elements, one element is visible, namely the element of visible form (rūpa-dhātu). Because colors and shapes have different distinctions here and there, they can consequently manifest expressions pointing to 'this' and 'that'; expression is called 'seeing' (darśana). Because there is that expression, it is called 'visible'. Another explanation: 'seeing' refers to the eye faculty observing visible form; because form possesses being seen by the eye, it is called 'visible'.
