Light one end of white sage, sweetgrass or palo santo and blow out flame. 
Pass smoke over item, person or around room, while setting your intention, silently or aloud.
Example: “Into the smoke I release all energies that do not serve me, all negativity that surrounds me, & all fears that limit me.” 

It will cleanse a space, a person’s aura and can also be used as incense during meditation.
***Do not leave unattended and extinguish in a fireproof container.***
