Liz Green: The Horoscope in Manifestation - How do we interpret transits and progressions from a psychological perspective?

Nevertheless, a great deal of what we assume to be predictable may not be predictable at all, once individual consciousness has begun to expand the levels at which we experience reality. For this reason I believe we need to try to live as though we have the freedom to work with our transits and progressions on a psychological level. We may then have room to transform or alter future events, or deal more creatively with anything that is our own creation due to the workings of unconscious complexes. As for those things about which we truly have no choice, we will find out soon enough, and can hopefully learn to accept and live with our necessity in a more tranquil spirit.

One of my main objectives in exploring this theme is to suggest that we may have more freedom than we think, on levels of which we might not initially be aware. If we can learn to work with the planetary movements with more insight and less of a literal, 'Uranus is going over whatnot and therefore such-and-such will happen' approach, we might discover what Pico della Mirandola meant when he said that human beings are co-creators with God. Literal-mindedness doesn't do us justice as astrologers. It can also be downright destructive, because there is, of course, such a thing as a self-fulfilling prophecy. Because our perceptions are invariably distorted by our individual complexes, we are inclined to interpret transits and progressions not according to what they might mean, but according to what our complexes tell us they will 'do' to us. Even the most orthodox 'traditional' astrologer is not really able to be objective when it comes to predicting events. We cannot even be certain what an 'event' really is, since so much depends on how and when the person registers what has happened. Our assumptions about the future are just as heavily coloured by our own psyches as our assumptions about the present.
