The South Node of the Moon occupies a distinctive and theoretically charged position in the depth-psychological astrology corpus. Where traditional Hindu astrology treats it (as Ketu) as a malevolent demonic force, the modern psychological tradition — principally through the voices of Dane Rudhyar and the Greene-Sasportas school — undertakes a sustained rehabilitation and reinterpretation. Rudhyar’s foundational contribution frames the South Node not as evil but as the signature of past achievement: inherited instinct, habitual facility, the line of least resistance crystallized through heredity and prior incarnational experience. The danger he identifies is not the node itself but the psyche’s tendency to regress into what is already mastered, surrendering forward development for the comfort of demonstrated competence. Sasportas extends this into a neurological metaphor, aligning the South Node with the instinctual brain stem — the seat of automatic, pre-reflective response — in structural contrast to the North Node’s cerebral-cortical aspiration toward self-reflective consciousness. Greene brings a Jungian coniunctio lens, reading the nodal axis as the sphere in which the Sun-Moon polarity is most urgently negotiated. Across the corpus the South Node thus functions as the symbol of psychological inheritance, the condensed residue of what has already been integrated — simultaneously a resource and a potential impediment to individuation.
the South Node in a chart does not have of itself an evil or destructive significance. If it has been called the point of ‘self-undoing’ it is because we have so often a way of following the line of least resistance
Rudhyar argues that the South Node represents inherited past-achievement and natural facility, becoming destructive only when the individual surrenders to it rather than using it as a platform for further development.
the south node corresponds to the instinctual seat of the b[rain]
Sasportas maps the South Node onto the instinctual, pre-reflective neurological substrate — the older brain — positioning it structurally as the automatized inheritance that the North Node’s higher psychological capacities must consciously transcend.

There seem to be many different ways of interpreting the Moon’s Nodes, ranging from the fatalistic Hindu approach (Rahu, the North Node, and Ketu, the South Node, are understood as demonic energies which always bring disaster) to the ‘past life’ reading of them
Greene surveys the interpretive spectrum — from Hindu fatalism to reincarnational and psychological readings — in order to establish the psychological approach to the nodal axis as the most analytically productive framework.

What is seen therefore through the Moon’s nodes is the relation between the ‘human’ will and the ‘divine’ will, between the conscious efforts at integrating an ego-centered personality and the super-conscious guidance or motivating urge
Rudhyar situates the nodal axis as the cosmological interface between ego-conditioned hereditary will and the transpersonal directive of Destiny, with the South Node representing the former pole.

I believe the nodal axis crystallises the relationship between Sun and Moon and reflects that sphere of life in which the coniunctio — the inner blending of the two principles — is most likely to manifest.
Greene proposes that the Moon’s nodal axis — including the South Node — serves as the locus of the alchemical coniunctio between solar and lunar principles, giving the nodes a central role in psychological integration.

South Node in the 5th, North Node in the 11th These people should be encouraged to become involved with group endeavours. There is a need to develop social and/or political awareness, to promote a common cause
Sasportas provides systematic house-by-house delineations showing the South Node as a zone of over-familiar, personally entrenched behaviour patterns from which the North Node direction offers developmental liberation.

as the south node in the 7th suggests, trying to derive her identity solely by being somebody’s wife was not going to work for her. She took a deep breath and willingly stepped into her north node in Leo in the 1st.
Sasportas illustrates through clinical case material how the South Node in the 7th house manifests as compulsive identity-merger with partners, with psychological growth requiring a conscious turn toward North Node individuation.

Uranus’ South Node is on a degree symbolized by: ‘Th[e…]’
Rudhyar extends the South Node concept beyond the Moon to planetary nodes, treating each planet’s South Node as the signature of established, habituated expression of that planetary principle.

no less than four planets plus the moon’s north node in the eighth house, and Uranus, fitting for the suddenness of the demise, placed precisely in the midheaven
Greene notes the Moon’s North Node as one of several significant chart factors in a ‘death chart,’ using nodal placement as a marker of fated or karmically freighted timing in a concrete case study.

the Moon’s North Node is in the twelfth house, implying power released through meditation or subjective introspection
Rudhyar briefly deploys the North Node’s house position in a chart analysis of Mussolini, treating it as an indicator of the channel through which collective unconscious forces operate, implicitly contrasting it with South Node release patterns.
