Daśapadārthī is a text of Indian philosophy and the Vaiśeṣika school only preserved in the Chinese translation made by Xuánzàng 玄奘 in 648 BC. The translation was included in the catalogs of East Asian Buddhist texts and subsequently in the East Asian Buddhist Canons despite clearly being not a Buddhist text. Daśapadārthī is almost unquestionably assumed to be written by a Vaiśeṣika 勝者 Huiyue 慧月 in Sanskrit reconstructed as Candramati or Maticandra. But is that the case? The author argues that (...) the original Sanskrit text was compiled by the Buddhists based on previously existing Vaiśeṣika texts for an exclusively Buddhist purpose and was not used by the followers of Vaiśeṣika. That would explain Xuanzang’s choice for the translation as well as the non-circulation of the text among Vaiśeṣikas. (shrink)
