opaalointi
Opaalointi, an Estonian folk custom, involves the ritualistic burning of dried herbs, often juniper or other aromatic plants, in a hearth or fireplace. This practice is primarily associated with the transition from winter to spring and is believed to purify the home and ward off evil spirits. The smoke produced is thought to cleanse the air and the dwelling, symbolizing renewal and the expulsion of negative influences.
The custom is deeply rooted in agrarian societies where the change of seasons held significant importance
While the specific details and frequency of opaaloienti may have varied over time and across different regions
