Channelling crystals are recognised by one of its faces (preferably the main or predominant face) having seven sides, and with its opposing face having three sides in a perfect triangle. Mainly these crystals are used as meditation and development tools, to gain inner clarity and bring light and wisdom into the inner mind. They may permit certain amounts and types of information to be retrieved, both from the Higher Self, and from outside sources. They will certainly aid and support the channelling process, especially for those just beginning this work. To use, place the 7-sided face on the 3rd eye, or place the thumb on that face with the hands resting in your lap and then enter your inner space.
