Why to wear the SikhKara on the left or right arm?
As what we learned from SSS Yogi Bhajan men should wear the Kara on the right hand and women on the left. He says that balances the dominating hemispheres of the brain accordingly. Guru Dev Singh (Sat Nam Rasayan) wears two Karas on the same hand. He says that that helps you to stay connected to yourself when you do a lot of healing work. The Indian Nihangs wear their Karas on both arms as the see themselves as not man and not woman, but as creation of God. That way both hemispheres are being balanced. Some Sikhs also believe that you should wear the Kara on the hand you use the most as it reminds you not to do anything unjust with that hand. In the end, I suggest that you try it out for yourself and wear it on the hand it feels better for you.
