Palo Santo or "Holy Wood" is sweet smelling wood that grows in Central and South America.  It is used in ceremony in a similar fashion as sage, however while sage is an excellent cleansing smoke, the smoke of Palo Santo is a direct messenger to the Divine and Spirit worlds.  Use Palo Santo any time you will be setting an intention or calling in new energy, such as before yoga, prayer, or meditation, when moving into a new home, while traveling, during a new moon ritual, or simply in the morning as you imagine your day.
