We can with reasonable confidence say that the Gāndhārī text did not belong to the schools responsible for the Pali Dhammapada, the Udānavarga, and the Mahāvastu; and unless we are prepared to dispute the attribution of any of these, this excludes the Sarvāstivādins and the Lokottaravāda-Mahāsānghikas, as well as the Theravādins (and probably, in company with the last, the Mahīśāsakas). Among possible claimants, the Dharmaguptakas and Kāśyapīyas must be considered as eligible, but still other possibilities cannot be ruled out.
