The symbolism of the number 4, as represented in the fourth Arcanum of the Tarot (The Emperor), signifies the Quaternary, which reflects the creative aspect of both divine and human will. This aspect will manifest itself in the creation of material forms. Following the Ternary— the vital principle that arises from the union of opposites— the Quaternary serves as its spatiotemporal expression, revealing itself through a structure characterised by densi-ty. This density supports the concrete manifestations of the spirit. The square and the cubic stone serve as geometric representations of this process, illustrating the stability of material-ised entities and their “fall” into a stable form.


In the context of astrology, we begin by analysing the relationships formed between the Elements assigned to the zodiac signs. At first glance, we observe that the vertices of the square inscribed within the zodiac circle encompass all the Elements in their various stages of development (see Trine). The connection to the number four is significant; for a form to stabilise in a dense physical realm, contributions from all elements are essential (see the Tetrapolar Magnet).

However, it is in the interaction between the Elements that we observe the tension created by adapting the creative principle to physical forms:

  • Fire vaporises WaterWater extinguishes Fire.
  • Earth chokes Fire – Fire (heat) dries up the Earth.
  • Air disperses the Earth – the Earth obstructs the Air.
  • Water weighs down (moistens) the Air – The Air agitates the Water.

These relationships, which have counterparts in both the psyche and in the formation of external events, suggest that square aspects create significant effects. Essentially, these configurations require individuals to manage their contradictions and navigate the adverse elements of existence. For example, Fire is characterised as warm and dry, while Water is cold and moist. Acting without tension means adopting an attitude of sacrifice, where one accepts the need to weaken Fire to balance it with the receptive quality of Water. At the same time, it involves giving up the stability of Water to ignite emotional states with Fire.


In judicial astrology, a square is often seen as an obstacle to achieving certain expectations or as resistance encountered across various aspects of human experience, whether physical, psychological, or related to destiny. It is considered a critical aspect; however, its impact largely depends on the overall configuration of the chart, the planets involved, concurrent aspects, and, importantly, the evolutionary stage of the individual consulting the chart.

The square embodies the adage “It’s easier said than done,” illustrating the challenges of translating potential into reality, whether in personal accomplishments, social achievements, or the overcoming of psychological and emotional barriers. While the square can be problematic, its greatest strength lies in its poor adaptability, underscoring its evolutionary potential.


In the transpersonal analysis of a chart, a square aspect presents a significant potential for realisation. The key to overcoming unconscious habits lies in the effort required to address and resolve difficulties. These protective mechanisms, as described in self-suggestion techniques, obstruct access to one’s true self and only allow us to examine what we believe ourselves to be. Consequently, the opportunities for change are sidelined by the self-deception we impose.

With its inherent connotation of resistance to change, the square aspect helps us identify psychological blocks that hinder the recognition of our true nature. How can we integrate this often-unresolved relationship? While a detailed response would be too lengthy, we can illustrate the concept with an example.

Moon square Venus

The Moon symbolises sensitivity and acceptance, embodying these values through its various associations. As Earth’s satellite, it reflects the sun’s presence and marks the rhythms of nature’s cycles. One of the Moon’s defining characteristics is its changeability; time governs existence, making it subject to transformation.

Venus, located within Earth’s orbit, plays a crucial role in the psychological and physical development of individuality. This interplay establishes balance and harmony among different aspects of life, which justifies Venus’s designation as the planet of love and affection.

Moon square Venus establishes, therefore, a significant relationship between the values of acceptance and relational balance. This aspect can create challenges in accepting changes arising from relationships rooted in strong emotional values or in character growth required for the success of the union. Instead, individuals may find themselves drawn to unstable relationships that involve a certain degree of suffering.

One potential manifestation of this aspect is the experience of having an emotionally distant mother. For men, this can lead to insecurity in relationships, while for women, it may result in a lack of confidence in their femininity. However, it’s important to note that this is an effect rather than a cause; the emotionally distant mother is a challenge that the individual may choose to encounter. Not everyone views this experience as a deficiency; for some, especially those with a strong sense of independence, it can be an evolutionary advantage.

At the core of the issue lies a vital understanding: the challenges posed by this aspect do not exist independently. Events, individuals, or circumstances do not inevitably dictate our fate. While we cannot avoid these challenges when they manifest, we have the power to transform them by channelling their energy toward positive outcomes. Specifically, in the case of the Moon-Venus aspect, this transformation requires sacrificing selfishness, which often leads to an inability to accept changes that may not initially seem beneficial. This concept applies particularly to our love lives and the experiences associated with houses influenced by this aspect.


When analysing planetary transits, significant changes or evolutionary potentials typically arise only with the transits of slow-moving planets. Based on historical frequency, we can anticipate a notable crisis in the areas affected by the houses of the horoscope. It’s also important to consider the symbolism of the planets involved and any recurring configurations.

Fast-moving planets in a transiting square have a more pronounced impact than those in a trine aspect. Because these phenomena are cyclical, they often pose challenges for managing physical and psychological resources and for interacting with the external world. For instance, a transiting square of Mars (every 172 and 515 days from the conjunction with a natal planet) can lead to increased energy expenditure, conflicts, and unilateral actions.
