Pumpkins scream in the dead of night. (I couldn't resist.)
When the night is its longest and darkest, the link between the world of the living and the world of the dead is at its strongest. This is actually a belief that shows up across cultures, Dia De Las Muertos for example, and religions, the Catholic equivalent being All Souls Day celebrated on November 1.This is the night when spiritual powers are at the strongest and is best for casting spells. This is also the night to remember friends and family we have lost.
First and foremost is your altar. Black candles represent death, while orange ones represent vitality and life. Gold and silver are also good choices as they represent the sun and moon respectively. Use myrrh or patchouli for incense, and decorate with small gourds, chunks of smoky quartz and onyx, and a cauldron. Divination tools, such as a Tarot deck or runes, also have a place here.
To celebrate make a wreath, carve a pumpkin (be sure to roast the seeds), make a mask of your shadow side (doubles as a costume), and build a besom (also known as a witch's broom). Tis the season for pumpkin and spices and Samhain is no exception. But, I don't care for pumpkin and despise nutmeg, so I'll be eating my weight in these ginger cookies instead. Most importantly, be thankful for the people you love who loved you and do a ritual to honor their memories.
Have a happy and safe Samhain!
