सिद्धान्तलक्षणम् (Siddhānta Lakṣaṇam)
The final definition of vyāpti, known as siddhāntalakṣaṇa, has been explained by Jagadīśa in this work. The final definition of vyāpti is: where pratiyogyasāmānadhikaraṇya tāsāmānādhikaraṇatyantābhāvāpratiyogitāvacchedakabhacchinam does not hold, their vyāpti stays in the same locus. Raghunātha Śiromaṇi comments on this definition of vyāpti. Jagadīṣa further explains this final definition of vyāpti.
