This chapter introduces Appaya’s Śivādvaita Vedānta works, paying special attention to its most important piece, the Śivārkamaṇidīpikā. The chapter first discusses Appaya’s doxography of Vedānta schools, the Caturmatasārasaṃgraha, and highlights how it might have been used to introduce Śrīkaṇṭha’s teachings to a wider scholarly audience and lend them authority in the process. It then discusses how Appaya creatively reads Śrīkaṇṭha’s commentary, with special reference to Śrīkaṇṭha’s theory of transformation (pariṇāmavāda), with a view to aligning its teachings with the doctrine of apparent transformation (vivartavāda) held by tenants of pure non-dualism (Advaita Vedānta). Finally, it investigates Appaya’s interpretation of the pāśupatādhikaraṇa (BS 2.2.35–38) in his Śivārkamaṇidīpikā, and shows how his commitment to Advaita Vedānta impacts his broad understanding of Śaiva scriptures and makes him read passages from those scriptures rather differently than his Śaiva co-religionists.
