If you only have one magickal housekeeping tool or ingredient, a white sage bundle should be it. This is because burning white sage lifts vibrations, releases stuck energy protects from negativity, and creates sacred space. If any sort of negative events takes place in your space, you can burn white sage to quickly and effectively purify the residual energy from the event. It is also just a good practice to burn it periodically for general purification. After you burn it, you’ll definitely notice a positive difference in the feeling and atmosphere of a room.
To burn it, just light the bundle and carefully shake it over a dish or the sink until the flame goes out but it is still smoking. Carry the a dish under the burning up tip to catch any falling ash, and move around the perimeter of each room you’d like to purify, taking as much time with each area as your intuition guides you to. You can also burn it around your body to purify your energetic body and aura.
