While attend an lecture, i was told that the shivalingam is made up of granite that has radioactive counterparts of Uranium, radon and many other elements. So pouring the water on the shivalingam compensate the effect of radioactive compounds.
And we are not allowed to touch The water after pouring on shivalingam
Question:- Is this reason correct or it just an scientific explanation of that practice.
Thankyou here is the reference
