I have heard Hindu citizens do the rituals this time period and no non-veg foods. There are so many peoples who are living nowadays society respect their oldest culture. So definitely follow old rituals and teach their children the importance of the culture. In fact you have made really delicious and spicy fish fried. It's mouthwatering dish.
I sometimes feel, old rituals are definitely worth following - they must have done quite a good amount of observations before coming up with these rituals. Even though, we have done progress in scientific research, most of the times, science agrees to what they found out.
