Impression Jasper is a stone of tranquility. Its energy unifies the many aspects of your life, by balancing yin and yang. Impression Jasper is known to absorb negative energy, align body, mind, spirit, and is also useful for shamanic travel.

Yin and yang represent duality, or the idea that two opposite characteristics can actually exist in harmony and complement each other.
