I have to say it. I have to! Friday the 13th is wonderful!
I will spare you the tirade into the roots of the superstition (being predominantly that of lunar cycles and goddess worship that became "passé" -understatement of the year- with the advent of monotheism. But feel free to read up on it here for starters. There are also more 'academic' sources if you are so inclined, just ask...me or Google.)
However, my reason for thinking Friday the 13th is wonderful is beyond that. It is even more than the fact that it is FRIDAY the 13th (that's *Friday* people!). THIS day unlike all others is a fantastic was to become positively self-aware. And it's easy! Because you'll likely be doing it already (i.e. worrying about mirrors that shatter when you sneeze in their general direction, black felines that may have possibly ever touched the same pavement as you are about to step on and evil spells bound to conjure up simeltaneously an epic bought of -now no longer pandemic- Swine Flu-and cause you to lose your job in an instant.)
You will be totally aware of all these thing and reflecting on all kinds of other 'hidden meanings' and the like. So turn this awareness to some good use today! Just make it a bit more focused: look for beauty instead of mirrors, words of gratitude instead of those that harm and love instead of cats (fine! That last one's subjective...maybe I'm more of a dog person, but you're picking up what I'm putting down.)
Celebrate your everyday today! Start a movement... Happy Friday the thirteenth!
