Blue Obsidian -  is a grounding stone that provides an instant connection from the Root Chakra deep into the core of the Earth. It will help to clean and remove negative energies in a sacred space or environment. It also assists in releasing those emotions/reactions that cause negative energy such as anger, jealousy, greed, resentment, etc. Once these energies are removed/released, Obsidian will help to keep the space protected.
Obsidian is used for healing and releasing energy blockages. It has a tendency to work quickly to move truths to the surface to be resolved. This allows both healer and subject a unique clarity as to initial cause of the issue, so that it can be dealt with. If you have a physical illness, that you believe has an emotional cause, Obsidian could be the fastest way to discover the cause, but you must be willing to face it and ready to correct it.
Obsidian can be very intense and one must be ready to confront their issues when working with this stone. Healers may use Obsidian to help those unable or unwilling to let go of the past.
