The Cesium Crystals are one of the tools that our Extraterrestrial brothers give us, usually in an outing.
They are first put into our hands were they are perceived like a pyramid of energy on each hand.
Next, The Semi-materialized "Cesium Crystal Pyramids" are received and incorporated into the chest, creating in this way an Eighth Chakra whose purpose is to allow assimilation of "manasic" energies streaming from the center of our galaxy; it also an aid in developing psychic faculties.
