Kyanite is one of my favorite crystals and I think everyone should have some in their metaphysical / crystal tool kit. I have several sizes and they are good for adding in groups of 2, or 4 to grids of 4 or more crystals.

It will immediately align all of the Chakras automatically with no conscious direction. It is considered to be a great facilitator of meditation and will aid you if you are having difficulty settling the mind when meditation or relaxation is desired.
