The historical Tsongkhapa flourished in the period immediately following the final redaction of the Buddhist canon in Tibetan translation (Tib. bKa' 'gyur, pronounced Kanjur). He presents a Middle Way (Sk. madhyamaka, Tib. dbu ma pa) philosophy, based on the works of the Indian philosopher Nāgārjuna (third-fourth century), and strongly influenced by the Indo-Tibetan Buddhist logico-epistemological tradition (Sk. pramāṇa, Tib. tshad ma) founded by the Indian epistemologists Dignāga and Dharmakīrti (fifth to seventh century). In it he strikes a balance between knowledge and praxis. He unerringly characterizes all statements about ultimate truths (Sk. paramārtha-satya) framed in positive terms as false, but develops a hermeneutics to retain the authority of correct moral statements on a covering (Sk. saṃvṛti) or conventional (Sk. vyavahāra) level. His most influential writing reconciles the philosophy of emptiness (Sk. śūnyatā) with the imperative of praxis embodied in a universal altruistic principle (Sk. bodhicitta). He gives pride of place to apparently antinomian tantric praxis without devaluing the centrality of ordinary moral life, and develops a distinctive analysis of dependent origination (Sk. pratītya-samutpāda).
