Obsidian is a result of volcanic molten lava cooling so fast it did not have time to crystalize, so it is a form of natural glass. Thus, energetically it works very quickly and powerfully. Like a mirror, nothing can be hidden, so all is revealed including things one might not want to look at. As such it is a force for catharsis and growth by promoting compassion & strength. At the same time Obsidian provides the protection, grounding and calming effects to heal from trauma, especially for sensitive people. It repels negativity and channels power into good. As a healer it helps find the cause of disease and aid to detoxify. Use it as an elixir for shock, pain or tension or wear it as a bracelet or pendant.
