It is not related to psychology but can use its language to associate certain astrological aspects or configurations with psychological types or states.
For example, in terms of depth psychology, a negative Moon-Saturn aspect is described as a state of deprivation (Saturn) of protective and motherly values (Moon), with all the consequences derived from it.
But since astrology is a symbolic view of reality, this is only one of the multiple layers of meaning that we can use to describe things from a specific point of view. Suppose we adopt a different level of representation, for example, the pathophysiological one. In that case, we can associate the aspect with colds, asthenia (lack strength), or the retention (Saturn) of liquids (Moon). In all these cases, the primary symbolic meanings of Saturn (the structure guaranteeing permanence and stability to the individual) and the Moon (the archetype of hospitality and gestation function) are “transmitted” by analogy to various levels of human experience.
We can only answer the second question in the affirmative. The predictive aspect of astrology is a deviation from its true meaning: to harmonise the individual – that is, to make them aware of their role in the world – by mirroring themselves in the celestial rhythms. The divination function in this context makes it possible to evaluate the times and ways in which to carry out the process. Still, the debasing of astrology has distorted its meaning, making astrological prediction a comforting phenomenon, if not a pastime, as in the astrology of newspapers and television broadcasts.
