Double Terminated Crystal – As the name suggests, these crystals have a point on each end. They have the capacity to both push and pull energy through their ends. By placing a double terminated crystal in between the chakras, they can then be used to move energy both upwards and downwards through the chakra column of the physical body. Double terminated crystals strengthen energy flow, and are especially useful when you need to share or exchange energy between you and another person. Double terminated crystals are very important to people doing healing work for themselves or others.
Smokey Quartz balances the root chakra and is generally thought of as a 'grounding' stone. But, it does much more than that!!  It is very useful for treating stress, depression, fear and panic.  It stimulates the desire for life and survival while giving the courage to make changes and break bad habits that no longer serve you.  Smokey Quartz is a great meditation stone, aiding the alpha state; use if for hypnosis also.  Some find this crystal to be a powerful protection stone, simply carry it with you when you feel you are in need of 'extra' protection.
