The Siva Sutras, The Yoga of Supreme Identity is a collection of seventy seven aphorisms that form the foundation of the tradition of spiritual mysticism known as Kashmir Shaivism. They are attributed to the sage Vasugupta of the 9th century C.E. It is believed that they are the words of Lord Shiva himself, and that each aphorism directs us to know Lord Shiva and his direction for us and our lives.
Vasugupta is said to have lived near Mahadeva Mountain in the valley of the Harvan stream. It is said that Lord Shiva came to him in a dream and instructed him to go to a certain rock on which he would find the teachings inscribed. This rock called Shankaropala is still visited by devotees. The other theory is that Lord Shiva taught the Siva Sutras to Vasugupta in a dream. Whatever the truth is these myths point to the traditional belief that the Shiva sutras are of Philosophical origin or revelation and are surely a very great product of Sanatana Dharma.
