A month back i have purchased a banalingam. Some sivachariars informed that the is not a banalingam and what i have is a Salagramam.My informed that it is UTCHAGA LINGAM or lingam which produces. Further he mentioned that the Lingam does not require any Abhisek and requires only Sandal post. I was trying to know more about this lingam. Would some one explai n what is Utchaga lingam. The lingam what i have has one cicle inthe form of garland, another smaller cicle right side. I will be grateful if somebody explain.
