This slender Kara is the light-weight sister of the classical 5 band steel style. It is discreet and feminine, yet in keeping with tradition and the intended deeper message.
The Kara has been worn for centuries as an Amulet of Protection. “It guards you from the outside, and also from the inside. The Kara reminds you not to do evil with your hands, and thus protects you from Karma. It is also like wearing an energetic soldier on your wrist, deflecting negative energy away from your aura.” https://blog.spiritvoyage.com/kara-the-protection-bracelet/
These energetic-magnetic effects strengthen the male (or active) energy when worn on the right wrist. When worn on the left wrist they strengthen the female (or receptive) energy.
Yogi Bhajan taught that wearing a Kara balances energy centres and protects the wearer from harm.
