Beltane is the ultimate fire festival. The third of three spring fertility festivals and named in honor of fire, Bel, itself. It has long been celebrated in northern Europe and is one festival that the Church was hard pressed to attempt to co-opt. The maypole beat out the crucifixion as a way of celebrating spring, hands down.
There is no wrong way to celebrate Beltane. Chances are there is a fire festival, Maypole dance or a drum circle near where you live. If not, and you don't want to start your own (those pesky neighbors again), simply do something outside. Walk, run, plant something, feel the sun on your skin. Light an orange or red candle, ask the Element of Fire to enter your life with it's passion and creativity. Honor whatever Sun God you converse with. This is the wild, passionate, masculine energy to balance the gentle, coaxing spring energy of Ostara. I'm not normally much on duality and balancing energies, but this is the obvious exception.
