White Sage Smudge Stick 10inch Cleansing
 
Smudging is the burning of sacred herbs for the purpose of cleansing and purification.
Smudging calls on the spirits of the sacred plants to drive away negative energies.
The smoke created by burning the herbs binds with any negative energies and carries them away as the smoke disperses you can smudge just about anything that needs cleansing.
If you move into a new home, it is nice to cleanse it of any residual energies from the previous tenants before perhaps blessing it to create harmony and peace.

Smudging is often performed to clear a sacred space before rituals, you can also smudge yourself to to cleanse and purify - especially if you have been weighed down with stress and worry.
Smudging is commonly used to cleanse crystals, before dedicating them for healing, and periodically to remove the energies they pick up from doing their work.
