The Great Table is subdivided into four lesser grids for the four elements: air, wind, fire, earth. And the four cardinal directions; east, west, north and south bound together by the cross-shaped Tablet of Union. They are used to call upon the aid of angels ruling over the four directions. The names of God and the angels to be used in the invocations are extracted from the tablets. The four tablets are often called the Enochian Tablets because the letters may be written in the Enochian alphabet also revealed to Dee and Kelley by the spiritual beings.

Spiritual beings must be evoked into our reality by human beings. Humans must open the gates and admit the servants of Coronzon. Evocation and invocation are not a part of the business of angels, but of humans. That is why the angels needed to go through the elaborate ruse of conveying the system of Enochian magic, with the Keys and the Great Table of the Watchtowers, to Dee. If the apocalypse is to take place, and if it is necessary for human beings to open the gates of the Watchtowers before it can take place, the angels first had to instruct a man in the correct method for opening the gates.

The Enochian communications teach not only that humanity itself must initiate the apocalypse through the magical formula delivered to Dee and Kelly, but that humans must be the physical agents that bring about the plagues, wars, and famines described with such chilling eloquence in the vision of St. John. It is we who will let the demons of Coronzon into our minds by means of a specific ritual working. They will not find a welcome place there all at once, but will worm their way into our subconscious and make their homes there slowly over time. In the minds of individuals that resist this invasion they will find it difficult to gain a foothold, but in the more pliable minds of those who welcome their influence they will establish themselves readily.
