Sushruta Samhita
भवति चात्र- अहं हि धन्वन्तरिरादिदेवो जरारुजामृत्युहरोऽमराणाम् । शल्याङ्गमङ्गैरपरैरुपेतं प्राप्तोऽस्मि गां भूय इहोपदेष्टुम् ॥२१॥
"I am the supreme and original god in the form of Dhanvantari. It is I who ward off disease and decay from the celestials. Formerly an inmate of the region of heaven, now I have incarnated on earth with the view to teach the Science of Surgery with all its allied branches of study to men."
