2. Prepare your space with proper airflow
When cleansing with sage, it’s crucial to have good ventilation. Open a few windows and doors to allow airflow, helping the smoke to carry away the energy you’re clearing from the space.
This airflow not only keeps your home ventilated but also symbolizes releasing negative energy. Writer Bridget Douglas recommends leaving your window open “for at least an hour after to air it out.” She also recommends using “house plants and/or an air purifier to clear the air after burning sage.”
