Obsidian is a fast stone. It was once molten lava that cooled so quickly it could not crystalize properly. This stone will move just as quickly in helping you expose weaknesses and secrets.
Obsidian helps us grow and brings forth negative emotions to be dealt with instead of hiding them away. It pulls from the root chakra, assisting with self-preservation, self-understanding, and self-esteem.
Obsidian is a very grounding stone, and it is also very protective. It will take negative energies away from us, block psychic attacks, and remove any negative influences from the spiritual world.
Black Obsidian is also a very creative help in our lives. It will force the spiritual world to be guided by our physical consciousness. Black Obsidian will pull those negative energies forth even more, forcing us to deal with our true selves and understand our feelings.
Root Chakra - the grounding Chakra which represents you being grounded to the Earth and the physical body. This Chakra is where many obstacles are stored that prohibit you from being happy and holding onto negative energy.
