The Spanish translation of Halloween is "El dia de las brujas" meaning "The day of the witches." In Pagan tradition, Samhain is regarded as the Witches New Years because it is a time where we celebrate the death of the goddess followed by her rebirth. A common Samhain practice is to write down ones new years resolution on a piece of birch bark or parchment and then burn it in an offering bowl whilst concentrating on it. This practice ensures success on the resolution as it is sent to the spirit realm when it is burnt.
So take advantage of this time! If you've lost a loved one in the past year, make a mute supper! If you want to astral project, there is absolutely no better time to try now! If you need to work on something to make you a better person, make a resolution and burn it! Don't just sit in your house waiting for trick or treaters to come by! Do something fun!
