In other works Greer has explained that there are three major theories of magic: or types of magic, if you will. Natural magic, as described in this work, is based on the idea that the universe is permeated by energies that are mutually dependent. Everything is spiritually connected and the magician tests, compiles and used knowledge of these connections to perform magical work. Planting by the signs, for example, relies on the connection of the moon with the life energies on earth and the manifestations of other energies in the astrological signs. The simplest form of moon magic is to work for increase during a waxing moon and for decrease during a waning one. So you would plant wheat or leafy vegetables when the moon is waxing, root vegetables such as carrots or potatoes when it is waning. An almanac will contain more detailed advice based on the sign the moon is in, with some days good for castrating livestock, others good for painting or for cutting hay.

A second form of magic is based on obtaining power or favor from supernatural beings. This is the classic figure of the magician safely within a circle guarded by sacred names and signs, invoking a spirit to do his or her will. Faust is our cultural type of this magician and there are many grimoires that describe the methods.

A third type of magic is probably more familiar to most modern readers on the subject. However according to Greer it really got its start in the work of Eliphas Levi and relies on the focus of the magician's will. The world is still seen as containing energies and spiritual powers, but the magician is part of the powers, not a mere technician working with them.

Natural Magic has been neglected as a systematic study. Many books of spells, magical oils, etc. rely on the methods of natural magic, but few explain the principles or prepare the magician to construct their own workings from basic principles as this work does. I recommend it to anyone interested in magic, and certainly for witches and Wiccans of all types. It includes a guide to natural substances and their magical properties, a guide to making amulets, potions, incense, etc. a guide to growing and using herbs and a basic introduction to plant alchemy.

I would consider this a must have for any coven library and only wish it had been available years earlier. ( )
