While some crop circles are hoaxes a lot aren’t, they are made by aliens. Aliens and angels are believed to be the same thing by many people, and crop circles are huge talismans of power. To cast your love spell locate a crop circle, usually aliens will create one nearby if you ask them to - they will hear you, ask them inside your head. Once you have a crop circle, stand within the circle and say silent to yourself:
Angels and aliens use your magic on me and bring my love - state name to me as fast as you can.
So mote it be!
Next, bend down and pick up a piece of straw from the crop circle and carry it around with you until your wish comes true. Aliens and angels tend to be very fast, so within a month results should manifest.
