Putting Coins into the River...
Putting coins into the holy river is considered as one of the spiritual task which is performed from ancient times.There is one scientific reason behind this .
In ancient times the river water was directly used for drinking purpose (Now this water has to flow through different filter process).In that times coins were made up of Copper.Drinking water which is stored in Copper vessel is good for health and it is as good as a medicine. The reason behind the putting the coin into river may be same, so that every one using the water of the river can be benefited with this natural medicine. It is good to drink a liter of water in the early morning which is stored in a clean Copper vessel.
Now the copper coins are replaced by steel, i think now its time to stop this performance..
