Keep negative energy out of your space with a little candle spell. It is a suitable spell for one room, rather than your whole house. You’ll need:
• Blue taper candle
• Square of white paper
Lay the paper out on your altar or table, and set up the candle in the center of it. Use a clear glass candle-holder if you have one, though any type will do. Sprinkle a circle of salt around the paper, so that all 4 corners of the paper are just touching the salt.
Light the candle right at the top of the hour (exactly 1 o’clock, or 2 o’clock etc.), and let it burn right down. When it’s done, carefully brush the salt onto the paper, and pour it down the drain. Bury the paper outside. All the bad energy in the room is now gone.
