Samhain is the Yin period of the year to Beltane's Yang. It is the balance of the forces of nature. Since this time of year is wonderful for banishing, it is one of my favorites to clean house!
Beyond the physical cleaning, take the time to cleanse the house of any negative vibrations as well. One of our traditions is to invite over a few select friends, or members of your coven, and have a cleansing party. Here is what we do:
Starting widdershins, we have each person add a palmful of Celtic Sea Salt to each corner of the house and say "cleanse and bless, cleanse and bless, may all who dwell here live happiest." Then have each person dip a small bouquet of Lavender (our herb garden) and shake sacred well water (we use Glastonbury Water)into each corner and over the threshold saying the blessing. We then give all a wand of White Sage Wand and cedar grass dipped in Frankincense and camphor oils to burn and use the smoke to (smudge) seal the windows and doors of the house saying "only good may enter here." Finally, each person stands with a lit white candle, grouped into the corners of the house and chants 3 times "bless all who enter, may they find the peace they seek."
We then sweep up the salt and bury it along with the wands, sprinkling a bit of the water over the mound.
