The earliest known appearance of the Hamsa hand was modern day Iraq, better known previously as Mesopotamia.
Here it could be seen in a lot of the jewelry and amulets worn by certain highly touted women.
From there it is said to have spread to Egypt as a two-finger amulet representing Osiris and Isis. After this it began spreading to different religions in several different forms- including Buddhism and Hinduism.
The Hamsa may mean many different things to many different people depending on whom you ask. Its symbology is interpreted differently amongst people, it means different things to Hindus and Buddhists.
For Hindus and Buddhists, it symbolizes the interplay of the chakras, which is the energy flow in your body, the five senses, and the mudras that effect them.
Each finger has it’s own energy:
Thumb- Fire element, solar plexus chakra.
Forefinger- Air element, heart chakra.
Middle Finger- Ethereal elements, throat chakra.
Ring Finger- Earth element, root chakra.
Pinkie Finger- Water element, sacral chakra.
In Buddhism, it symbolizes the chakras to a less extent, but the mudras are still important nonetheless.
Often times, the Hamsa is used to ward off what’s known as “the evil-eye”
