Petalite is a high vibration crown chakra stone.  It accelerates psychic skills while providing strength and protection especially during astral travel and vision quests.  I feel that the stone anchors your spirit and body when doing any traveling or psychic work. 
 
It connects you with angels, ancient civilizations, your guides, and your totem animals.  Petalite is best summed up as a stone of tranquility, gentle upliftment, manifesting, awareness expansion, and psychic enhancement.  Since the energies from the stone will flow in the direction of your thoughts, keep your mind focused on positive outcomes to achieve them.
