A gateway, or aperture, crystal has a cup-shaped depression within it that is large enough to hold liquid. Gazing into the liquid center provides a gateway to other worlds and enables one to travel through past, present, and future. It is an excellent stone for preparing a gem elixir that aids spiritual vision and psychic faculties. A key crystal has an indentation or aperture in one of its sides, which narrows as it penetrates the crystal. This indentation is usually, but not necessarily, three-or six-sided. It provides a doorway to unlock parts of the self that are normally kept hidden or to access hidden information of any kind. Meditating with one of these crystals reveals what is being hidden from you, especially by your subconscious mind, sweeping away illusion. It is an excellent tool for letting go of anything that holds the soul back and for tie-cutting.
