The Seba library treats Doppelgnger in 9 passages, across 3 authors (including von Franz, Marie-Louise, McGilchrist, Iain, Victor Turner, Victor Witter Turner).
By living a virtuous, religious life, he develops a double in the Beyond, and the moment of death is the moment of reunion with the other half.
Von Franz locates the Doppelgänger within Persian-Gnostic myth as the transcendental complementary self — the soul's other half held in reserve beyond incarnation — whose reunion at death consummates the divided human being.

"I am thy own self, the other half.'' This is an archetypal idea. In many primitive societies, it is thought that on entering this world, every human being is only a half, the other half being the placenta.
The double is framed as a universal archetypal structure — the personality's unincarnated remainder, located in the placenta or the Beyond — whose recovery is the telos of the religious life.

if a dream figure doubles, that always means it wants to become conscious that it touches the threshold of consciousness and thereby reveals the double aspect.
Von Franz establishes a precise semiotic rule: doubling in dream imagery signals an unconscious content pressing toward consciousness and revealing its inherent two-valuedness.

he lights a candle and sees a sleeping man with fair, wavy locks
Von Franz's close reading of the literary Doppelgänger encounter — the protagonist confronting an uncanny sleeper in his own flat — dramatizes the moment of meeting one's autonomous double as both terror and threshold.

the belief that a person you know very well is actually being 'impersonated' by an impostor, a condition known, after its first describer, as Capgras syndrome.
McGilchrist anchors the Doppelgänger in neuropathology, interpreting Capgras syndrome as a right-hemisphere deficit in which the familiar becomes uncannily alien — the clinical correlate of the double motif.

these two powers always fall into each other through an enantiodromia, as do all unconscious opposites; both are unconscious opposites because they are gods, which means basic archetypal drives in the psyche.
The doubled antagonist figures von Spat and Fo are interpreted as polar archetypal drives caught in enantiodromia, with the human protagonist suspended between them — a structural analog to the Doppelgänger dynamic.

von Spat and Fo both want to get his soul. When von Spat goes too far in his power play, he snaps into Fo, and you will see that when Fo goes too far into his other play, he snaps round into von Spat.
The mirroring and mutual invasion of opposed spirit-figures illustrates the Doppelgänger's deeper logic: the double is never merely an image but an autonomous force competing for the ego's allegiance.

twins are one person and that they are birds: 'Their single social personality is something over and above their physical duality, a duality which is evident to the senses.'
Turner's ethnographic material on twinship — the paradox of dual bodies sharing a single ritual identity — provides a structural parallel to the Doppelgänger's collapse of individual singularity into uncanny doubleness.

the anomalous may be sacralized, regarded as holy. Thus, in eastern Europe, idiots used to be regarded as living shrines, repositories of a sacredness that had wrecked their natural wits.
Turner's discussion of anomaly and sacralization contextualizes the Doppelgänger as a culturally liminal phenomenon: doubles and threshold figures alike are removed from the structured social order and invested with numinous significance.
