（7）「舍其现存的与已成的而他获得舍」，如是说则称关于考察的中立为舍，是名「观舍」。

Ñ(IV,163): Equanimity about insight is a name for equanimity consisting in neutrality about investigation described thus: 'What exists, what has become, that he abandons, and he obtains equanimity' (M. ii, 264-65).

Notes in Chinese translation: 「观舍」（vipassanupekkhā），《解脱道论》「见舍」。
