In Native American tradition cedar is used to carry prayers to the creator. It is used to bridge the gap between heaven and earth. It also seems that the cedar tree has connections with power and the sun through many varying traditions such as Sumerian legend, Cabalistic lore and Eqyptian mythology. It is often associated with breaking the misuse of power or powerful forces that may be having a negative influence.
Sweetgrass has similar properties to sage, popularly being used as a purifier of places, objects and people to encourage positive energy and dispel old and negative vibes. Belief has it that when sweetgrass is burned, a prayer is sent to heaven on the smoke. Its properties make it ideal for using in quiet moments of contemplation, as well as when wanting to create an air of purification.
