Scorpio, a fixed, watery sign, is assigned to Nun. Scorpio is ruled by Mars (Key 16, The Tower), and is said by modern astrologers to be the sign of exaltation of Uranus (Key 0, The Fool). Scorpio governs the sex-organs, and is therefore closely associated with reproduction. It is, moreover, connected with the eighth house of the horoscope, which is called the house of death. Thus this sign is directly connected with the title of Key 13. The correspondingcolor is blue-green. The musical tone is G-natural.
Imaginative Intelligence is the mode of consciousness attributed to the letter Nun. Qabalists say: "It is the ground of similarity in the likeness of beings." That is, it is the basis of the resemblances which are transmitted through the reproductive function. The choice of the adjective "imaginative" is in accordance with the doctrine of Ageless Wisdom that causation is mental. All changes are primarily changes in mental imagery. Change the image, and ultimately the external form will change.
Death, the title, is, as we have said, obviously related to the astrological meaning of Nun. The Bible says death is the last enemy to be overcome. But how? "Overcome evil with good. Love your enemies." In these two brief sentences is the whole secret.
The forces of change which result in physical death are inimical only because we misunderstand and fear them. They are forces connected with reproduction, and by right use of imagination they may be tamed and transformed, so that they can be utilized for indefinite prolongation of physical existence. Death, like every other event in human life, is a manifestation of law. When we understand the law we can direct the forces of change so as to overcome death. Yet understanding never will be ours until fear, not only of dying, but of death itself, has been overcome by right knowledge, and by right interpretation of the phenomena of physical dissolution.- PFC
