Shiva Advaita (Devanagari:शिवाद्वैत, Kannada: ಶಿವಾದ್ವೈತ, Śivādvaita), also known as Śiva Viśiṣṭādvaita or Shaivite qualified nondualism is a Shaivite school of philosophy from Southern India that was founded by Śrīkaṇṭha Śivācārya during the eighth century.
It is not known whether Śrīkaṇṭha Śivācārya's work was completed before or after Ramanuja's.
[4] Sri Appayya Dikshita contributed further to Shiva Advaita by expounding Śrīkaṇṭha's philosophy in his Sivarka mani dipika.
[4] Śrīkaṇṭha does not deny Nirguna Brahman, which is central to Advaita.
[5] In contrast to Śrīkaṇṭha, who considers his Brahma Sutra Bhasya Viśiṣṭādvaita (qualified non-dualism), which affirms the supremacy of Saguna Brahman, Appayya affirms a form of pure non-dualism and recasting Śrīkaṇṭha's work in an effort to establish Shiva Advaita in his Śivādvaitanirṇaya.
