How to create a magical circle

In a magic circle, each cardinal point is a Reference to an element: Water (West), Fire (North), Earth (South) and Air (East).
Its fabrication varies with the time, date, location, and season. One must also seek the spirits that we want to invoke, the star or planet that presides at the the precise moment of the action.
On a square white fabric of linen, of about 1.50m side, draw three circles from the same centre, the first one with a 1.40m diameter, the second 1.30m and the third 1.20m. Between the three circles, there are two areas of 10cm within which the names we will indicate here below, should be written.
Do not use common ink but a rather a mixture of a few drops of holy water and some ash obtained by burning a blessed piece of buxus, making an easy mixture to write with, with a paintbrush.
