Obsidian is a unique crystal which is volcanic glass, it is lava. Lava flows and nothing can stop it. Lava does pushes through no matter what and does not care what ever is in its way. In this same way, Obsidian will remove all obstacles in your way, all blockages will be broken through. So if you have blocks in your life preventing you to step forward, then Obsidian is your stone. Obsidian is also very reflective, very shiny when polished, and it can help you to look within and be reflective, and help you to see in others, your own limitations. A great protection and grounding stone.
