仁王經疏 1.118

1.118

言八除入者，三八勝處德。所言八者，一內有色想觀外色少、二內有色想觀外色多、三內無色想觀外色少、四內無色想觀外色多，內無色想觀外諸色青黃赤白，復為四種。諸宗出體，同前遍處。

The phrase "eight eliminations-entrances" refers to the third virtue of the eight bases of mastery. What are termed the "eight" are: (1) internally having the perception of forms, observing external forms as few; (2) internally having the perception of forms, observing external forms as many; (3) internally lacking the perception of forms, observing external forms as few; (4) internally lacking the perception of forms, observing external forms as many; and internally lacking the perception of forms, observing external forms of blue, yellow, red, and white, which again constitute four kinds. The positing of their essence across the various schools is the same as for the universal bases above.
