About Obsidian:
Black Obsidian is a stone of inner-reflection, truth, and growth.  It takes you deep into the subconscious mind, forcing you to face your true self, your shadow side.  It magnifies inner negative energies so that they can be fully experienced and then released.  This 'putting to rest' of the past helps to encourage new growth of the soul.  This healing goes all the way into past lives, if necessary, and affects all levels of our being.

With Black Obsidian, it is possible to manifest spiritual energies on Earth. This is because Black Obsidian grounds spiritual energies into the physical plane, and helps align them with the conscious will.  It teaches that empowerment has nothing to do with personal power, but everything to do with channeling power for the good of all.

Obsidian is a protective stone.  It forms a shield against external negativity and absorbs negative energies from within the environment.  It provides strength in times of need, blocks psychic attack, and chases away negative spiritual influences.

Physically, Obsidian helps reveal the cause of disease.  It detoxifies and dissolves blockages and tension in the physical and subtle bodies, including hardened arteries. It aids circulation and promotes physical digestion.  It reduces the pain of arthritis, joint problems, cramps, and random injuries. It is also known to shrink an enlarged prostate.
