ઉપાધ્યાય મેઘવિજયગણિ વિરચિત ચિંતામણિ પરીક્ષા

Summary

This article introduces and comments on Chintamani Pariksha, a Navya‑Nyaya treatise authored by the Jain scholar Upadhyaya Meghavijaya. The treatise critically examines definitions and logical relations in the context of the doctrine of vyapti (pervasion or invariable concomitance), which is essential for valid inference. Meghavijaya refines earlier definitions that were either too broad or too narrow. The article provides the Sanskrit text and Gujarati explanation of the first discourse, where Meghavijaya defines vyapti as the unbroken coexistence of the probans and the probandum in all possible loci. He examines faults such as over‑extension and under‑extension and uses examples like smoke and fire to illustrate correct reasoning. The article outlines the second discourse, which continues the logical analysis and responds to objections from other philosophical schools. It emphasises Meghavijaya’s methodological rigour and his contribution to Jain logic and situates the work within the broader Navya‑Nyaya tradition.
