According to the Shaivism sect, the highest form of Ishvar is formless, limitless, transcendent and unchanging absolute Brahman, and the primal Atman (soul, self) of the universe. There are many both benevolent and fearsome depictions of Shiva. In benevolent aspects, he is depicted as an omniscient Yogi who lives an ascetic life on Mount Kailash as well as a householder with wife Parvati and his two children, Ganesha and Kartikeya. In his fierce aspects, he is often depicted slaying demons. Shiva is also known as Adiyogi Shiva, regarded as the patron god of yoga, meditation and arts.
