Library Crystal means "Libraries of Light". It has one main terminated point with other smaller castling terminations growing out from the main point. It is one crystal, surrounded by many smaller crystals, which has the appearance of a crystal castle.
Library Crystals promote access to sacred 'akashic' knowledge written in the language of light. They act as energy conduits through which the universe can relay specific information that is essential for humanity at this time in our evolution. The double spiraling that occurs during the crystal's growth makes this powerful tool extremely sensitive to receiving universal frequencies and human thought forms simultaneously, refining the essence of universal knowledge and converting it into messages that the human mind is capable of comprehending.
