By Itihasa we usually only mean the epics Ramayana and Mahabharata. But have a look at the following passage/verses from Linga Purana (Tr-J.LShastry-Part1, Ch-26):
For the propitiation of the eighteen Puranas beginning with Brahma, for the propitiation of the eighteen Upa-Puranas beginning with Saura, and for the propitiation of holy Itihasas starting with Saiva he shall touch his ears and cardiac region.
Here, actually the process of Achamana (the ritualistic sipping of water) and the allied rites are being described.
Now coming to the passage, I know that we have 18 Puranas and the 1st one among them being the Brahma Purana. Similarly, I am also aware of Saura Purana, an Up-Purana.
- But which is the Shaiva Itihasa being talked about here?
