The Avacchedakatānirukti, a supplement by Gadādhara Bhaṭṭācārya (circa 1604–1709) to the commentary Dīdhiti on the Tattva Cintāmaṇi written by the great philosopher Raghunātha Śiromaṇi (circa 1477–1547), deals with the interpretation of avacchedakatva, the individuality of invariable concomitance in inference (vyāpti), elaborating upon Raghunātha Śiromaṇi’s treatment of the topic. In his own commentary, the Subodhā, Prof. N.S. Ramanuja Tatacharya clarifies the most difficult portion of this śāstric text, and renders it accessible by presenting it in simple and lucid language.
