翻譯名義集 1.21

1.21

梵語【多陀阿伽陀】亦云怛闥阿竭，後秦翻為如來。《金剛經》云：「無所從來，亦無所去，故名如來。」此以法身釋。《轉法輪論》云：「第一義諦名如，正覺名來。」此以報身釋。《成實論》云：「乘如實道來成正覺，故名如來。」此約應身釋。

Sanskrit *tathāgata*, also called *dātājiājié*, was translated in the Later Qin as 'Thus-Come' (如來, Tathāgata). The Diamond Sūtra says: 'Coming from nowhere and going nowhere, hence he is called the Tathāgata.' This explains it in terms of the dharmakāya. The Turning of the Dharma Wheel Treatise says: 'The supreme truth is called "Thus" (*tathā*), and right enlightenment is called "Come" (*āgata*).' This explains it in terms of the saṃbhogakāya. The Tattvasiddhi-śāstra says: 'Riding the path of reality (*tathatā*) to come and attain right enlightenment, hence he is called the Tathāgata.' This explains it in terms of the nirmāṇakāya.
