I am going to be away visiting friends in Essex for Samhain itself (sadly missing the Carmarthenshire Pagan Community ritual as a result), yet it just wouldn't be right not to have an altar dedicated to my Beloved Dead at this time of year. A bit like not having Christmas decorations I suppose!
I wrote last year about the form my personal Samhain ritual normally takes, so I won't repeat myself. But I will suggest you take a look at this video, of the Bay Area Reclaiming community's Samhain Spiral Dance ritual. This event has been held annually since 1979, and now attracts hundreds of participants (including this year, my friends Georgia, Anne-Marie & Will). I just can't imagine attending a ritual that big - the energy must be amazing. Perhaps one day I shall be able to attend. Or perhaps one day, there will be a Spiral Dance in the UK. Oh well, I can dream...
Samhain Blessings to you.
