Having born in India, I have come across various set of rules for which I have never got satisfactory answers. For instance, Hindus believe right hand to be a pious one in comparison to left hand! For example, generally we eat by hands, and we use our right hand to so. But if we see someone eating with left hand, it seems weird! This thought of right-left hand has been rooted so deep down us from our childhood that we become judgmental on right-left hand manners even without our notice!
What is so special about right hand, and so improper about left hand? One theory is that we use left hand for toilet purpose and hence it is considered as impious! This helps in terms of hygienic criteria to some extent(P.S.: Indians use water for toilet purpose and not the toilet-paper). But if somebody cleans hands properly after toilet, then this reason of hygienic exists no more.
We need to use our right hand for religious process too. Using of left hand is not acceptable there. If you’re giving money to someone, people prefer that you give it with your right hand. Some people feel uncomfortable if you land your left hand to give money!
What’s your take on this?
