Double terminated crystals have distinct points at both ends. A double termination radiates or absorbs energy at both ends concurrently. This causes it to channel energy in two directions at once. A double terminated crystal integrates spirit and matter and offers an effective bridge between two energy points.
These are useful to absorb negative energy and break old patterns. They are sometimes used in overcoming addictions. When placed on the third eye, double terminated stones can increase telepathic ability.
