Shiv lingam

In the Nirgun-Sagun state Shiva is worshiped as the Shivalingam
A glance at the rounded, elliptical, an-iconic image of Shivalingam placed on a circular base (known as Peedam), which is found in the Sanctum Sanctorum (Garbhagraha) in all Shiva temples, has given rise to various interpretations, without realizing the scientific truths discovered by the ancient Hindu sages. The practice of worshipping Shiva Lingam as the holy symbol of Lord Shiva, has been from time immemorial.
The worship of Shiva Lingam was not confined to India and Srilanka only. Lingam was referred to ‘Prayapas’ by the Romans who introduced the worship of Shiva Lingam to European countries. The statutes of Shiva Lingams were found in the archeological findings in Babylon, a city of ancient Mesopotamia. Further, the archeological findings in in Harappa-Mohanjo-daro, which yielded numerous Shiva Lingam statutes, have disclosed the existence of a highly evolved culture long before the Ariyan’s immigration.
