Śākyakīrti 釋迦稱 (Sanskrit Śākyakīrti “Glory of the Śākya”; sometimes equivalently rendered as Buddhakīrti; 尊者 bhadanta honorific in the colophon) was an Indian Buddhist ācārya of uncertain dates, presumably of the late sixth or seventh century. He is known to East Asia exclusively as the author of the short Yaṣṭi-śāstra 手杖論 (KR6o0062), translated into Chinese by 義淨 (Yìjìng) at the Táng court between 695 and 713. The work is a verse-and-prose abhidharma-style polemical treatise structured around the metaphor of dependent origination as a “walking-staff” supporting the practitioner. He may be the same as the Buddhakīrti cited in late Indian abhidharma lineages or in Vasubandhu’s Vyākhyāyukti tradition, but no certain identification is possible. No biographical information beyond the colophon is available.
