(一)契證真理。大乘義章卷一（大四四‧四八一下）：「證會名之為入。」
(二)解知事物之意。無量壽經卷上（大一二‧二六六中）：「入眾言音，開化一切。」
(三)指梵語、巴利語 āyatana 之舊譯，新譯為處。即根境相涉入而生識稱為入；如十二入，新譯作十二處。〔唯識二十論〕（參閱「十二處」343、「處」4782）
(四)心或心作用之根據或端緒之意。維摩經卷上（大一四‧五三九中）：「是身如毒蛇、如怨賊、如空聚，陰界諸入所共合成。」同經卷中（大一四‧五四六上）：「求法者，非有色受想行識之求，非有界入之求。」
(五)進入某種境地。俱舍論卷十七（大二九‧二七三中）：「忍觀行人能入正定。」[佛光電子大辭典]

陳義孝編, 竺摩法師鑑定, 《佛學常見辭彙》

（術語）悟真理謂為入。大乘義章一曰：「證會名之為入。」【又】解知事物曰入。無量壽經上曰：「入眾言音。」淨影疏曰：「入謂解也。」【又】根境互相涉入而生識，謂之入。如十二入。新譯言十二處。大乘義章八末曰：「根塵互相順入亦名為入。」止觀五曰：「入者涉入。」【又】二入【參見: 本條。十二入見三科】
