阿羅漢譯言不生。以畢竟不生於三界五趣中故也。又涅槃之涅，亦言不生，眾法常住而無始生也。又梵云阿耨波陀，譯言不生。真言之阿字，不生，以諸法之本初不生故也。又不生為如來之異名，以如來常住不生不滅故也。凡諸法觀為不生者，佛道之樞鍵也。智度論三曰：「阿名不，羅漢名生，後世中更生是名阿羅漢。」涅槃經曰：「涅言不生，槃言不滅，不生不滅名大涅槃。」智度論四十八曰：「菩薩若一切語法中聞阿字，即時隨義。所謂一切法從初來不生相，阿提（Ādi）秦言初，阿耨波陀秦言不生。」楞伽經四曰：「不生即如來異名。」
anutpatti; anutpāda. Non-birth: not to be reborn, exempt from rebirth; arhanis mistakenly interpreted as 'not born', meaning not born again into mortal worlds. The 'nir' in nirvana is also erroneously said to mean 'not born'; certain schools say that nothing ever has been born, or created, for all is eternal. The Shingon word 'a' is interpreted as symbolizing the uncreated. The unborn or uncreated is a name for the Tathāgata, who is not born, but eternal ; hence by implication the term means "eternal". ādi, which means"at first, " "beginning","primary", is also interpreted as 不生 uncreated.
一不生 (一)梵語 arhan。音譯阿羅漢。得阿羅漢果者，不再受生於三界五趣之中，即永入涅槃，不受生死之果報，故稱為不生。〔大智度論卷三〕 (二)如來之異名。如來常住不生不滅，故稱為不生。〔楞伽經卷四〕 (三)「涅」字之義，謂眾法常住而無始生。據南本與北本涅槃經卷五載，涅言不生，槃言不滅，不生不滅，稱為大涅槃。 (四)梵語 anutpāda。音譯阿耨波陀。大智度論卷四十八（大二五‧四O八中）：「阿提，秦言初。阿耨波陀，秦言不生。」p1281
