This particular stone is excellent for inner peace, releasing of negativity, union of the heart and the will, attraction of what one emanates and communicating with non physical beings. It helps one release negative patters from the emotional body and raise to a more positive vibration. Prehnite with epidote will help one release ego-identification with past wounds as well as depletion of depressed emotional states.
