Kashmir Shaivism is a group of nondualist Tantric Shaiva exegetical traditions from Kashmir that originated after 850 CE. This tradition is also termed the Trika school and was actually pan-Indian, also flourishing in Oḍiśā and Mahārāṣṭra. The Tantrāloka, Mālinīślokavārttika, and Tantrasāra of the Kashmirian Abhinavagupta (975–1025 CE) are formally an exegesis on the Mālinīvijayottara Tantra, although they also drew heavily on the Kali-based Krama subcategory of the Kulamārga.
Kashmir Shaivism claimed to supersede Shaiva Siddhanta, a dualistic tradition which scholars consider normative tantric Shaivism. The Shaiva Siddhanta goal of becoming an ontologically distinct Shiva (through Shiva's grace) was replaced by recognizing oneself as Shiva who, in Kashmir Shaivism's monism, is the entirety of the universe.
The school is run by Amit Raina, born in Srinagar-Kashmir, India in a Brahmin family. His grand father was disciple of Swami Ram Ji who is from the lineage of Abninavagupta. His mother Krishna is a master in Sanskrit and father Dwarka Nath is a great follower of lord Shiva. Being born in the Kashmir Shaivism Tradition and having interest in spirituality from young age, he grew around great shaivite masters. Knowing that there is more to life than what you see with your eyes and what you perceive with your mind,he started practicing meditation and yoga from young age. In the city of Pune while working as an Engineer in a deep meditation he had a strong vision after which he left the comforts of his life and traveled all over the Himalayas and stayed in various ashrams.
