Smudging (burning sage) is a ritual that originated from Native American tradition for healing, clearing and it's sometimes used in religious ceremonies. The original meaning of the ritual was that the rising smoke carried the request to Spirit. Now-a-days, Sage is often used to remove household odors, and is said to alleviate airborne germs as well. Native Americans burned sage to clear both mind and home. Smudging is the act of clearing and releasing negative energy. Many people use it before you move into a new house.
