of the intriguing verses, of later date of course, in the Rigveda refers to the place
where the Ganga, the Yamuna and the ancient Sarasvati met, presided over by Someshvara.
Al-Biruni refers to a Soma Purana which has not been traced so far.
All these facts are only set out to show that Shiva, Somanatha,
Shiva worship, Somavidya and the order of Shaivayogis point to the worship of Shiva having
its origin in the pre-historic period; its relics can still be found in rituals of a
repulsive character, with some obscure sections of the cult followed in far away
places. The sect of aghoris, for instance, live in funeral grounds and besmear
themselves with ashes following Shiva in His aspect of Bhairava.
