Saiva Agamas from Vijaya to Vathula come under the Rudra Bheda classification, said R. Narayanan in a discourse. Some of the Rudra Bheda Agamas are Santana, Sarvokta, Parameswara, Kirana and Vathula. The following are the Upa Agamas for these Rudra Bheda Agamas: Lingadhyaksha, Suradhyaksha, Sankara, Amaresvara, Asankhya, Anila and Dvandva for Santana; Sivadharmottara, Vayuprokta, Divyaprokta, Isana and Sarvodgita for Sarvokta; Maatanga, Yakshinipadma, Paarameswara, Pushkara (Paushkara), Suprayoga, Hamsa and Saamanya for Paarameswara; Gaaruda, Nairruta, Neela, Ruksha, Bhanuka, Dhenuka, Kaalakhya, Prabuddha and Buddha for Kirana; Vathula, Vathulottara, Kaalajnana, Prarohita, Sarva, Dharmatmaka, Nitya, Sreshta, Suddha, Mahanana, Visva and Visvaanmaka for Vathula.
Both Siva Bheda Agamas and Rudra Bheda Agamas were large in size. In the Siva Bheda classification Yogaja and Cintya have one lakh verses each; Kaarana has one crore; Amsuman has five lakhs and Suprabheda has three crore verses. Vijaya, Nisvasa, Agneya, Makuta, Vimala, Chandrajnana, Mukhabimba, Prodgita, Lalitha, Siddha, Santana, Sarvokta, Paarameswara, Kirana and Vathula are some of the Agamas in the Rudra Bheda classification.
