Black Obsidian is a very powerful and protective stone. It repels negativity, disperses unloving thoughts, blocks psychic attack and removes harmful spiritual influences. It is also extremely efficient at blocking geopathic stress or soaking up environmental pollution. This is a stone without boundaries or limitations that works extremely fast at uncovering personal truths, flaws, weaknesses, blockages and our shadow-side. It is merciless in bringing forth the truth, from the past or present, so the problems can be dealt with from their roots. With intention, Black Obsidian can help us to face all of our negative energies within, experience and release them. All Obsidians are molten lava that cooled so quickly they had no time to crystallize. It grounds spiritual energy in the body and provides a grounding cord from our body to the center of the earth. This stone induces creativity and self-control.
