Within the depth-psychology corpus, Sun and Moon function as the primary pair of psychic opposites — irreducible polarities whose dynamic tension organizes both the individual psyche and the symbolic universe of alchemy, mythology, and astrological interpretation. Jung roots the pair in the fundamental structure of consciousness itself: the Sun symbolizes the sorting principle that raises contents above the psychic threshold, while shadow and unconscious correspond to the lunar domain. Von Franz extends this in her alchemical readings, where the coniunctio of Sun and Moon enacts the paradoxical unification of conscious and unconscious conflict, the very goal of the opus. In the astrological tradition, Greene and Sasportas treat the luminaries as the two master significators of selfhood — the Sun as the trajectory of individuation and creative identity, the Moon as the instinctual, embodied, receptive vessel — whose angular relationship (lunation phase) encodes the shape of a life. Rudhyar situates them philosophically within geocentric symbolism as complementary principles of light and periodicity, masculine and feminine, spirit and matter. Across these traditions, tensions persist: whether the pair is primarily cosmological or psychological, whether their union signifies integration or dissolution, and whether lunar priority (nomadic, pre-solar worship) or solar primacy (agricultural, patriarchal) represents the older stratum of human experience.

I think it is important to be as clear as possible about the basic meanings of the Sun and Moon. Howard and I have both spoken about the Moon in relation to change, material life, and the cycles of the body and the instinctual nature.
Greene establishes the Sun and Moon as the foundational dyad of psychological astrology, differentiating their meanings through the lunation cycle and the Moon's Nodes as a reflection of their relationship.

The sun then says that through it one reaches to any height, one is raised to any height; that is, the sun is that which lifts up... Then the moon says to the sun: "You need me just as the cock needs the hen, and I constantly need your effect on"
Von Franz articulates the alchemical dialogue between Sun and Moon as a mutual dependency: the solar principle elevates and perfects, while the lunar principle provides the indispensable receptive ground for that elevation.
von Franz, Marie-Louise, Alchemy: An Introduction to the Symbolism and the Psychology, 1980thesis
life itself would present the conflict, on the one hand in the sphere of the moon, and on the other in the sphere of the sun; the one is a conscious and the other an unconscious conflict.
Von Franz maps the Sun/Moon dyad directly onto the conscious/unconscious opposition, arguing that their spheres together encompass the fundamental paradoxical duality of all psychological phenomena.
von Franz, Marie-Louise, Alchemy: An Introduction to the Symbolism and the Psychology, 1980thesis
Behind the shut door the moon receives its soul from the sun and the sun takes away the beauty of the moon, which becomes quite thin and weak. That means the coniunctio takes place in the new m
Von Franz reads the alchemical coniunctio as an exchange between Sun and Moon at the new moon — the soul passing from solar to lunar — constituting the innermost moment of the opus.
von Franz, Marie-Louise, Alchemy: An Introduction to the Symbolism and the Psychology, 1980thesis
The Sun and the Moon are known as the givers of light. Light and life become inseparable, for darkness and night but too often mean death. Sunlight dispels fear, brings to the senses a clearer perception of objects.
Rudhyar grounds the archetypal significance of Sun and Moon in primordial psycho-physiological experience, identifying solar light with life-force and lunar light with the mysterious, magical, and periodic.

At New Moon, the Moon is at its innermost point within the Earth-orbit. At Full Moon, it is at its outermost point outside of the Earth-orbit. Subjectivity and objectivity.
Rudhyar interprets the New Moon/Full Moon polarity as a cosmological expression of subjectivity versus objectivity, aligning the lunation cycle with the rhythmic duality at the heart of psychological life.

This separation gives rise on the one hand to consciousness, whose symbol is the sun, and on the other hand to the shadow, corresponding to
Jung identifies the Sun with consciousness and implicitly the Moon with shadow/unconscious, anchoring the solar-lunar dyad in the structural architecture of the psyche.

The Moon then keeps increasing in light until it reaches the opposition to the Sun, which is the Full Moon... The Moon then begins to wane, to decrease in light, as it travels back toward the Sun.
Greene provides the technical foundation for lunation-phase interpretation, demonstrating how the angular relationship of Sun and Moon encodes a cyclic psychological biography.

take someone with the Sun in Aries and the Moon in Cancer... The Sun may want to move forward, take classes, give lectures, pursue degrees, or open businesses. The Moon might prefer to stay in bed or not do anything because it feels frightened.
Sasportas illustrates the intrapsychic conflict between Sun and Moon as competing subpersonalities when they occupy incompatible signs, demonstrating the practical psychological stakes of their tension.

The Sun symbolized the most important function, that of being the very source of the life-force... The Moon had then no significance as the satellite of the Earth — because that also was entirely irrelevant in a geocentric system.
Rudhyar historicizes the symbolic meanings of Sun and Moon within geocentric cosmology, insisting their significance is experiential and archetypal rather than heliocentric-astronomical.

The union of the full moon and the full-grown Sun is one form — the astronomical — of that sacred marriage which in many parts of the ancient world was celebrated at midsummer.
Harrison identifies the astronomical conjunction of full Sun and full Moon as the cosmological substrate of the hieros gamos, linking the solar-lunar dyad to ancient ritual and sacred marriage traditions.

Did not moon worship precede sun worship in the Semitic religions?... The pre-Islamic cult was of the stars and the moon. The nocturnal sky is exceedingly impressive to one who travels by night.
Jung engages the historical question of whether lunar worship preceded solar worship, situating the Sun/Moon polarity within a developmental account of religious consciousness.

in that connection of the moon with mind, one mustn't understand mind in the modern philosophical sense... Primordial man projected this upon the moon.
Jung argues that primordial humanity projected the discovery of subjective mental life onto the Moon, establishing its archetypal association with the interior, nocturnal, and fantasmatic dimensions of mind.

Why your Sun Sign may not fit you; how the physical features of the sun as a celestial body reflect its astrological meanings; the Sun as both the center of the solar system and the center of our being.
Cunningham frames the Sun as the astrological center of selfhood and the Moon as equally significant in the psychic makeup, establishing their joint primacy as the luminaries of psychological astrology.

If the Sun is unaspected, we need to think about the myth of the solar hero, to get a sense of what this energy looks like in its most primitive form. The most creative dimension is the raw, powerful creative force.
Greene links the unaspected Sun to the mythic solar hero archetype, showing how the solar principle in its unmediated form manifests as both creative potency and dangerous inflation.

The Moon also aspects itself by hard angle (conjunction, square, opposition) every seven years, so it has a cycle in relation to its natal placement just like transiting Saturn does.
Greene maps the Moon's cyclical hard aspects onto developmental timing, paralleling the Saturn return cycle and anchoring lunar symbolism in the psychology of life-phase transitions.

the Sun has been called the cause of the becoming (birth, genesis), growth, and nourishment of all visible things... This association of the Sun and its inclined circle with becoming and mutability and so with 'the Different' suggests that the movement of the Sun is the actual movement of the Different.
Plato's Timaeus establishes the Sun as the cosmological cause of visible becoming, associating it with the motion of the Different — the principle of mutability — which the Moon uniquely shares among the planets.
