Generally, Vaishnavas follow the Pancharatra Agamas, Shaivites follow the Shaiva Agamas, and Shaktas follow the Shaiva Agamas. But long ago, there was a group of people in Kashmir who followed the Shakta Agamas but adopted Shiva as their Ishta Devata. That group evolved into what we now call Kashmir Shaivism. Because it has its roots in Shakta Agamas, it subscribes to a monistic philosophy, as opposed to philosophical Shaivite sects like Shaiva Siddhanta which are more dualistic in their philosophy.
Now the most famous Kashmiri Shaivite philosopher was Abhinavagupta, who lived in the 10th century. Similar to Ramanujacharya, Abhinavagupta had a lot of Gurus; I've seen sources that say he had 12 Gurus. So my question is, who are all the Gurus of Abhinavagupta, and what Guru Paramparas did they belong to?
So far I've found information on four Gurus of Abhinavagupta:
Bhattenduraja - He was in the Parampara of Kallata Bhatta, who was a shishya of Vasugupta, the author of the Shiva Sutras, which are the defining text of Kashmiri Shaivism. Either Kallatta Bhatta or Vasugupta himself composed a work called the Spanda Karika which is the canonical commentary on the Shiva Sutras (although it's not a really a verse by verse commentary). Either way, Kallata Bhatta wrote a Vritti or commentary on the Spanda Karika. In any case, Bhattenduraja taught Abhinavagupta about poetics.
Lakshmanagupta - He was the shishya of Utpaladeva, the author of the Ishwara Pratyabhijna Karika, an important work in Kashmiri Shaivism. Utpaladeva was the shishya of Somananda, the author of the Shivadrishti, which in my view is a splendid example of the narcissism of small differences; Somananda focuses on criticizing the Sphotavada school of Bhartrihari, which is the philosophical school that agrees most with Kashmiri Shaivism. Now Somananda was a shishya of Vasugupta whom I mentioned above, but that's not the only lineage he's associated with; he also claimed to be a biological descendant of Durvasa's mind-born son Tryamabaka, whom I discuss here. In any case Lakshmanagupta taught Abhinavagupta about the Pratyabhijna school of Kashmiri Shaivism.
Shambhunatha - He is said to have belonged to the lineage of Durvasa's mind-born daughter Ardhatryambaka, as described on page 157 of this book. Ardhatryambaka seems similar to Durvasa's mind-born son Tryambaka whom I discuss here. I don't know anything about the lineage between Ardhatryambaka and Shambhunatha. But Shambhunatha was the one who initiated Abhinavagupta into the Kaula Tantras, and he's seems to be the one whom Abhinavagupta viewed as his main Guru.
Vamananatha - According to Wikipedia, he taught Abhinavagupta about "dualistic Shaivism", which may refer to the Shaiva Siddhanta sect. But I don't know anything more about Vamananatha.
So does anyone have a complete list of Gurus of Abhinavagupta along with the Paramparas they belonged to?
