The Siva Sutras
The first great initiate recorded in history of this spiritual path was Vasugupta (c. 875-925). Vasugupta formulated for the first time in writing the principles and main doctrines of this system.
A fundamental work of Shaivism, traditionally attributed to Vasugupta, is the Shiva Sutras of Vasugupta. Traditionally, these sutras are considered to have been revealed to Vasugupta by Shiva. According to myth, Vasugupta had a dream in which Shiva told him to go to the Mahādeva mountain in Kashmir. On this mountain he is said to have found verses inscribed on a rock, the Shiva Sutras, which outline the teachings of Shaiva monism. This text is one of the key sources for Kashmir Shaivism. The work is a collection of aphorisms. The sutras expound a purely non-dual (advaita) metaphysics. These sutras, which are classified as a type of Hindu scripture known as agamas, are also known as the Shiva Upanishad Samgraha (Sanskrit: śivopaniṣad saṅgraha) or Shivarahasyagama Samgraha.
