The heavenly lights are a magic of purity that comes from items that were touched by the great vision of the Apparaitions of Fatima. The heavenly lights give insight and visions. The visions are of the future in which you may direct them. Directing them means you may ask but not change what you see. You can prevent bad things by knowing what they are though. A example of this is if you saw a car accident while riding with someone you would know not to.
The insight part will allow you to know your personal future and how to fix or direct it. This helps in life in so many ways. To get a direct speaker you may use the tarot cards while wearing this necklace. You may also use this while using the pendulum or any other divination tool.
The last thing this piece does is to create a cleansing energy that washes over you the entire time you wear it.
