Black Obsidian helps you find Joy... by cutting out the pain!
It activates and heals the sacral chakra, and is an extremely powerful and fast-acting crystal, and should be used with caution for Crystal Healing. 
 
It can bring negative emotions and unpleasant truths rushing to the surface, which must be confronted before peace can return. Many people find Obsidian’s effects overwhelming and prefer to use a gentler stone for healing. 
 
Black Obsidian is a very protective stone. It is said to form a shield against toxic energies by absorbing destructive energies from the environment. Because of this, it should be cleaned regularly in running water. Be careful of the temperature, as Obsidian is volcanic glass and can fracture.
