Obsidian is molten lava that cooled so quickly it had no time to crystallize. Obsidian is a stone without boundaries or limitations. As a result, it works extremely fast and with great power. Its truth-enhancing, reflective qualities are merciless in exposing flaws, weaknesses, and blockages. Nothing can be hidden from Obsidian. Pointing out how to ameliorate all destructive and disempowering conditions, Obsidian impels us to grow and lends solid support while we do so. It needs careful handling and is best used under the guidance of a qualified therapist as it can bring negative emotions and unpleasant truths rushing to the surface. Under skilled guidance, its cathartic qualities are exceedingly valuable. It provides deep soul healing. Obsidian can facilitate in going back to past lives to heal festering emotions or trauma that has carried forward into the present.
Gold-Sheen Obsidian is particularly effective for scrying. It takes you into the future and the past and deep into the core of a problem. It shows what is needed for healing, but other crystals will be needed to achieve healing. Psychologically, Gold-Sheen Obsidian eliminates any sense of futility or ego conflict. Releasing ego involvement, it imparts knowledge of spiritual direction. Used in healing, Gold-Sheen Obsidian balances energy fields.
