A Caim Is a Celtic word. It means an invisible circle you put around yourself for immediate protection if you feel under threat. Draw an invisible circle around yourself with your right index finger by extending your arm towards the ground and turning clockwise with the Sun at day, or the Moon at night. As you do this, become aware that you are safe and encompassed by the love of God and Goddess, that you are encircled, enfolded and protected.

Celtic and Pictish - early Celts and their priests, the Druids, had their own form of alphabet known as “Ogam Bethluisnion”, which was an extremely simple alphabet used more for carving into wood and stone, than for general writing, while Pictish artwork was later adopted by the Celts, especially throughout Ireland (???)
