For hundreds of years, White Sage (Salivia Apiana) has been considered a scared, purifying plant. Native Americans started the tradition of burning its dry bundled leaves, during their purification ceremonies and healing sessions, to cleanse a space or person of all evil spirits or negative energies. 
Palo Santo (#Holy Wood# in Spanish) has been part of the South American culture for centuries. 
The wood of this wild tree from the Amazon rainforests, was traditionally burned by Incas and Shamans for spiritual purifying, energy cleansing and healing. 
The combination of the earthly aroma of White Sage with the soothing balsamic scent of Palo Santo provides a perfect environment for meditation.
