The Seba library treats Syzygy in 8 passages, across 4 authors (including Hillman, James, Papadopoulos, Renos K., Stein, Murray).
These torturing incursions of soul into spirit and spirit into soul are the syzygy in action. This is the coniunctio. Because of the anima-animus syzygy, psychology cannot omit spirit from its purview.
Hillman identifies the syzygy as the living dynamic of coniunctio — the mutual invasion of soul by spirit and spirit by soul — and argues this makes spirit indispensable to psychological inquiry.

In 'the realm of the syzygies' 'the One is never separated from the Other.' If anima belongs archetypally to this pair, we 'can hardly lay claim to say anything about the concept of anima' without speaking also of animus.
Hillman, citing Jung, establishes the syzygy as an archetypal law of inseparability: phenomenologically, anima cannot appear without animus, making isolated analysis of either pole conceptually impossible.

Much of what psychology has been calling ego is the animus-half of the syzygy. This leads into a job for another time: an examination of the notion of 'ego' and a comparison of it with 'animus.'
Hillman advances the provocative thesis that ego theory in analytical psychology covertly describes the animus pole of the syzygy, collapsing two distinct concepts and calling for critical re-examination.
, Anima: An Anatomy of a Personified Notion, 1985thesis
Essential to thinking in syzygies is thinking in genders. Unfortunately, the next step in analytical psychology has been identifying these genders with actual men and women, coupling kinds of syzygies between man-and-anima, woman-and-animus.
Hillman distinguishes legitimate archetypal gender-thinking inherent to the syzygy from its problematic literalization onto biological sex, which he identifies as a distorting move in mainstream analytical psychology.

The archetypal perspective of the syzygy will always perceive events in compensatory pairings. This must be so, for in 'the realm of the syzygies' 'the One is never separated from the Other.'
Hillman argues that the syzygy functions as an unavoidable perceptual frame — an archetypal compulsion that structures psychological observation itself into compensatory polarities.

If we start with the idea that men and women each have both an anima and an animus, this statement takes on a completely different meaning. We are closer to the ancient Greeks' idea that the spirit inspires the soul.
Papadopoulos surveys post-Jungian revisions that deconstruct the gendered polarity of the syzygy, noting that assigning both anima and animus to each person fundamentally alters the syzygy's theoretical structure.

The first four chapters of Aion function as a brief general introduction to Jung's psychology, covering the concepts of ego, shadow, and animus/anima, and a first pass at the theory of the self.
Stein locates the anima/animus dyad — the syzygy's primary expression — within Jung's systematic introduction in Aion, situating it as a preparatory stage before the full theory of the Self.

Jung felt that they had intuitively anticipated and imaginatively projected what has been verified in modern times. The lively imagery of alchemy differed markedly from the stylised and sexless expressions of medieval Christianity.
Samuels contextualizes the alchemical coniunctio — the practical and symbolic precursor to the syzygy concept — as Jung's key discovery of an historical precedent for depth-psychological ideas about paired opposites.
