Shiva
The Shaiva Puranas, particularly the Shiva Purana and the Linga Purana, present the various aspects of Shiva, mythologies, cosmology and pilgrimage (Tirtha) associated with him. The Shiva-related Tantra literature, composed between the 8th and 11th centuries, are regarded in devotional dualistic Shaivism as Sruti. Dualistic Shaiva Agamas which consider soul within each living being and Shiva as two separate realities (dualism, dvaita), are the foundational texts for Shaiva Siddhanta. Other Shaiva Agamas teach that these are one reality (monism, advaita), and that Shiva is the soul, the perfection and truth within each living being. In Shiva related sub-traditions, there are ten dualistic Agama texts, eighteen qualified monism-cum-dualism Agama texts and sixty-four monism Agama texts.
