@RijuDutta_84 A small correction : Mahashashthi being ষষ্ঠ, it is veg in a section of households. By the way, where is India placed in the hunger index of nations? The answer to that will make all these discussions irrelevant.
@hvgoenka I think it's the name of the ritual, "Ganga Aarti". I have seen it done on the bank of Kopai river in Birbhum, near Kankalitala temple. (All rivers meet the sea after all, and all the seas are connected!)
