These are the seven famous Nayas or metaphysical view-points of looking into the nature of things. Of these, the first three, Naigam, Samgraha and Vyavahåra have for their subject-matter dravya or substance, and the remaining four beginning with Riju-sutra have for their subject-matter Paryayas-Phenomena. It is important to note here that like quality (TU), mood (TH17) also comes within the perview of Parydya with this difference only that while quality inheres in substance, mood (41) inheres in both, -substance and quality.
With Nayavad ends the second part the Jain Logic, the Logic of Consistency being the first part.
