Most practitioners of the Sacred Arts and Occult Sciences eventually began working with fumigation for spiritual cleansing i.e. incenses like sage, or frankincense. However, if you don’t have either previously named incense then you can make an emergency incense using ordinary powdered cinnamon and a few spritz of extra virgin olive oil cooking spray and form it into a cone. Use a fire proof container like an cleaned ash tray or you can use a ceramic saucer and simple lit your homemade cinnamon incense cone with a match.
Your D.I.Y. customized cinnamon incense cone of about half an inch will burn for about 10 - 15 minutes. You can make a much larger one of course but remember the bigger the cone the longer it will take to consume. Then take whichever incense and hit the four corners of the area your magickal, or sorcery, or spiritual, or witchcraft work area. Also most important pass that smoke over yourself. The incense smoke with raise the vibration of both the room and yourself and cleanse out any unwanted energies or uninvited entities that don’t belong.
One final note - even though your D.I.Y. cinnamon incense cone in a fire proof ash tray or on a ceramic dish do not leave it burning unattended nor leave burning near anything flammable.
