Paintings and statues of Gods raising their right hand mean that you are welcome on the right side of God. Being on the right side of someone means you are the closest to them. It means you are the most important to them.
That is why the right hand is up.
The left hand is the idle hand and an idle hand is the hand of the devil.
Sooooo... enjoy hell. Jk jk
Lol
But yeah left hands is the idle hand. That is why people used to believe being left handed was a sign of the devil.
Also, in most cultures it is customary to greet with the right hand (shaking hands) and also holding utensils or eating food with your hand. The left hand is for cleaning your booty.
In the Hindu mythology Gods raising their right palm is shown to say that they are blessing the person looking at the picture. Even our elders bless us by raising their right palm and putting them on our head when we bend down to touch their feet
Another fact: touching your elders' feet and then touching your own forehead symbolizes that even the dust of your feet is precious to us. It is a way of seeking blessing and showing respect. Sorry for the long post.
