A Selenite wand pointed at the third eye sends energy that may feel like a gust of air going through the forehead and out the top of the head. Its energy can clear energy blockages, induce inner alignment, facilitate spiritual attunement and promote healing. It can make it possible for one to consciously meet one's spirit guides or guardian angels and receive inner guidance.
