Black Obsidian powerfully eliminates negative energies in oneself and one's environment. It is like a psychic vacuum cleaner, cleansing the auric field of disharmony, negative attachments, astral "junk," as well as one's own anger, greed, fear, resentment, etc. It is a strong grounding stone, stimulating the root chakra to make its connection with the Earthstar chakra below the feet and deep into the core of the Earth.
It is useful for all types of scrying, including spirit communication. It is also a strong stone of spiritual protection. In additional, it helps brings one's own Shadow material out of exile, allowing it to be transmuted through the heart. It aids in recalling the exiled bits from unconscious, even from past lives. This is a great aid to healing the body and soul.
Black Obsidian harmonizes with Jet, Black Tourmaline, and Smoky Quartz for grounding. Moldavite can raise Black Obsidian's vibration for self-transformation. Amber brings a healing influence. Alexandrite and Oregon Opal assist in using Black Obsidian to view past lives. High-vibration stones such as Phenecite, Scolecite, Natrolite and Azeztulite provide enhanced psychic abilities and a high spiritual focus to one's work with Black Obsidian.
