Vasugupta

He paved the way for later scholars for a cultural and religious renaissance in Kashmir which continued for centuries till the advent of Islam.

His principal disciple, Bhatta Kallata spread the Shiva Sutras, and wrote Spanda-karika in the 2nd half of the 9th century.

[2] Vasugupta is regarded by some as the founder of the system of Hindu philosophy known as Advaita Shaivism of Kashmir, or Trika.

[2] Vasugupta's Shiva Sutra is an important Yoga text, foundational to the Trika system of Kashmir Shaivism.

The text has been extensively commented upon by Indian authors, and some manuscripts have been translated into English, such as by Mark Dyczkowski[1] and by Jaideva Singh.
