For reasons which are allied to the connection existing between the constitution and the health, the good aspect of the Moon to the Sun at birth is an excellent augury, for it indicates co-ordination between the organic and functional. Where this co-ordination exists there is always considerable power of recuperation, so that illness is easily overcome and the balance of power restored in the system.
Malefic planets rising and afflicting either the Sun or Moon indicate prolonged ill-health, and most frequently some permanent hurt to the body.
When predisposition to illness is shown in the horoscope, the particular affection can be determined by the Sign which the afflicting planets hold. Thus if Saturn afflict the Moon from Aries, you will judge some hurts and obstructions in the head, chills and colds, influenza, coryza, &c. Similarly Mars in Leo would indicate functional defects of the heart due to accelerated action and overstrain, such as result from fevers.
A good aspect of the planets Jupiter and Venus is of material help in counteracting the influence of malefic aspects or evil positions.
Thus it will be seen that the health may be judged entirely apart from the constitution, the planets which are in aspect to the Moon being of first consideration, and next those which may be rising at the time of birth.
CHAPTER IV
HOW TO READ CHARACTER AND DISPOSITION
Ptolemy says: “Mercury is the ruler of the rational soul, the Moon of the animal soul.” By this he would mean, no doubt, that Mercury has relation to the faculty of the mind, while the Moon is related to brain function. There are certain attributes of the mind which are distinctive of the human being, and certain other qualities which are common to man and the lower animals. These latter are under the dominion of the Moon, while Mercury has chief signification of the rational faculties.
