In astrology, several predictive techniques are available. Beginners are often familiar with at least the Transits, the Solar Revolution, and the Symbolic Directions techniques. There are many more. Why should we use one technique rather than another? Actually, they are complementary, even though some astrologers deem that the transits technique is the most reliable one. It is widely believed that Secondary Progressions reflect the evolution of the personality, whereas the other techniques are more linked to more concrete events (Symbolic, Solar Arcs, and Primary Directions, particularly). It is important to bear in mind that the universal principle of prediction is based on the resonances of the current sky with the aspects of the natal chart, and on the repetitions of the same themes by different techniques. Predictions are all the more reliable and precise when several methods yield results which converge towards the same meanings.
One of the most remarkable features of our solar system is that nearly all of the revolutions and rotations are in the same direction. From a point high above the north pole of the solar system the planets are revolving about the sun and rotating about their axes in a counterclockwise direction. This holds true also for the asteroids. If the planets and asteroids were formed from merely random accretions the would be an even mixture of the directions of revolution and rotation. The sun itself also rotates in a counterclockwise direction.
When a child is born it is immersed in an atmosphere charged with the stellar vibrations peculiar to that moment, which are stamped upon each atom of the sensitive organism by the air inhaled
with the first breath. This planetary baptism is the basic cause of all the child's characteristics and idiosyncrasies; it gives certain tendencies which remain through life. This is the radix or
radical horoscope which we carry about in our bodies and, whether we know it or not, it is the root of all events in life.
But the planets do not remain stationary in the positions they occupied at the time of our birth; their progress is eternal as is that of our Father in Heaven, and in time they form aspects other than those which they made at birth. These progressed configurations are called Directions, and they mark the time in life when events are due to occur.
Directions are of two kinds, primary and secondary.
Primary directions are formed between the progressed planets and their positions at birth. If, for instance, the Sun was in no degrees of Aries and Jupiter in 25 degrees of Leo at the birth of an individual, then, as the Sun moves forward in the Zodiac at about one degree a day, it will be trine with Jupiter about twenty-five days after birth. The system of time measurement of the planetary progression in general use reckons each day after birth equal to a year of life. Thus the said individual will meet with a very fortunate event in the twenty-fifth year.
Aspects may also be formed between two progressed planets; to follow out the example given in the last paragraph, Jupiter would progress one or two degrees in the twenty-five days. It would then be in 26 or 27 degrees of Leo, and after the Sun had passed the trine with the radical Jupiter and it would come to the trine of the progressed Jupiter and this would prolong the fortunate influence for several years, though it should be borne in mind that the effect of aspects between two progressed planets is not so strong as when the configuration is between a progressed and a radical planet.
Secondary directions are formed by the progression of the Moon to aspects with the planets, particularly the radical. These lunar aspects are of vital importance, for unless the primary directions are supported by aspects of the progressed Moon which are of a similar nature, they come to naught. To illustrate by reference to the example of the Sun trine Jupiter. If at the time when that culminated, the progressed Moon had been in Gemini 25, sextile to both the Sun and Jupiter, that would have given a wonderfully favorable impetus to the event signified by the direction, but had the Moon been in Taurus 25, square to Jupiter it would have prevented the event and caused trouble instead. Had there been no secondary lunar direction at the time the event would have remained latent until the next lunar aspect of the progressed Moon either brought it out to life or withered it. Lunations (New Moons) are also powerful factors in energizing directions, particularly if they are eclipses.
