I know that the answer to the question "Which of the school of thought has the base name at the beginning of the sect name?" is in "Early history of Shaivism is difficult to determine. However, the Śvetāśvatara Upanishad (400 – 200 BCE) is considered to be the earliest textual exposition of a systematic philosophy of Shaivism. Shaivism is represented by various philosophical schools, including non-dualist (abheda), dualist (bheda), and non-dualist-with-dualist (bhedābheda) perspectives. Vidyaranya in his works mentions three major schools of Shaiva thought— Pashupata Shaivism, Shaiva Siddhanta and Pratyabhijña (Kashmir Shaivism).". Can you tell me what it is? 


Shaiva Siddhanta
