Obsidian removes blockages and debris from past lives and reverses previous misuse of power. This stone blocks psychic attacks and removes negative spiritual influences. Obsidian brings deep-seated emotions and issues to the surface.
 
This works extremely fast so make sure you are pairing this with other crystals to help you through issues that rise to the surface. 
 
Carved crystal skulls are a symbol of hope and represent “death” which in turn represents new beginnings. Just like in tarot reading the Death card is a card of not just the end of something, but the start of something new. A new beginning. A new start. From death, comes life.
