Gnostic Warrior is truly a great treasure trove of spiritual reading. In the article above, they discuss possible connections to the culture of the Arab Bedouins and the Celtic Druids.
It’s hard to believe that people who lived thousands of miles away from one another may have had any connection. But as I mentioned in A Shared Spiritual Origin in Celtic Europe and Indo-Aryan India, it is very probable that the spirituality and culture of the Celtic people had its origins in the migration of the Aryan tribes from the Near East (either Iran or Northern India) across Europe. Some say some of these Aryans also spread elsewhere. If they migrated as far as Ireland, it’s not hard to imagine that their influence may have touched areas closer to home.
Gnostic Warrior discusses some of the interesting connections between the Pre-Islamic Arab Bedouin tribes and the practices of the Celtic Druids. The worship of the God Baal (whose name sounds a lot like the Celtic Bel), the tradition of poets and bards, rituals performed under oak trees, animal sacrifice, fire worship, and a similarity in dress.
I’m not here to verify that this theory is true. I’m just saying that it’s interesting reading and that you should decide for yourself whether this connection could be true or not.
