Natrolite is one of the two or three most powerful stones for stimulation of the third-eye and crown chakras. It can actually cause the merging of these chakras into one huge energy center. Natrolite's energy moves beyond the confines of the physical body, activating one's conscious link with the eighth through fourteenth chakras above the head."
