According to the colophons of the Old Uyghur Daśakarmapathāvadānamālā (DKPAM), this collection of Buddhist birth legends was translated from a Tocharian A (tohri) source which in turn was based on a Tocharian B (kusan) original. A Tocharian B fragment from the Paris Pelliot collection presents a close parallel to the legend of Kalmāṣapāda and Sutasoma of the Old Uyghur DKPAM. This legend is so far not attested in Tocharian A. Although the existence of a Tocharian A intermediary text cannot be excluded, the parallel is so close that the Old Uyghur text may also have been translated directly from Tocharian B.
