Why so confusing ?

I am trying to explore my religion but I do see a lot of people with different set of rules ,, for example a lot of people say that eating non veg should be prohibited but a huge population do eat non veg and being a bangali we eat a loot of fish and meat on the other hand cow is sacred for us but south indians especially kerala people do eat beef ,, every community has their own different set of rituals while doing puja,, I do follow hindu rituals and traditions and try to follow life according to bhagwat geeta but on the same hand I dont believe that God intervein in the daily activities of our life its rather our karma that matters .
