Prehnite Rock Stone helps in healing, connect with beings on the higher spiritual planes, and enhances spiritual growth. It was known in the past as a stone of magic, and this may have been because it so strongly connects you to the Divine Mind. It's very useful opening Hart Chakra in Meditation.
Prehnite is an important crystal, as it is a powerful healing stone on many levels. However and wherever it is applied, it will not only work directly on the problem in the 'here and now', but will also calm and clear the effects of trauma and illness from the corresponding subtle bodies, and even work in other dimensions. Unlike most minerals, prehnite from different localities will display similar properties, with mild variations according to other included minerals and crystal formation. Prehnite is a general balancer and very calming.
