Blue Apatite is associated with the mind and can stimulate the intellect allowing expansion of knowledge. It is a stone of manifestation attuned to the future allowing you to keep planning what is next in your life. Similarly, it can increase the strength and frequency of lucid dreaming. Place a piece inside your pillowcase to increase and strengthen your visions.
If you wear or carry Apatite daily, it may have beneficial effects by suppressing hunger pangs.
