Simulcarnation is the simultaneous incarnation of more than one personality emanated from the same Oversoul (the "Disk" in Robert Monroe's and Bruce Moen's terms, or Causal body). Where conventional reincarnation imagines a single soul living one life after another in a neat sequence, simulcarnation describes the Oversoul projecting several personality "threads" into physical existence at once—sometimes into overlapping historical periods, sometimes into what are experienced as different "dimensions" or paradigms of reality.
The key is that no single incarnation is the whole soul. Only a finite portion of the Oversoul's energy is committed to any one body; the remainder persists as an intact field of consciousness, fully capable of sustaining other concurrent lives. In the CTM's computing analogy, these concurrent personalities behave like multithreaded execution across isolated processes: each runs its own "user session," usually largely partitioned from the others, while a higher-order state manager—the Causal Oversoul / Higher Ego—oversees, synchronises, and integrates them without directly executing any of them itself.
Michael Newton's regression subjects independently reported the same thing: particularly ambitious souls occasionally choose to animate two or even three bodies at once (usually against their guides' advice, and usually only once, finding it too strenuous; Michael Newton, Destiny of Souls, p. 117). Simulcarnation names this phenomenon and locates it precisely within the CTM's tiered architecture.
Simulcarnation is not the everyday personality "splitting" or being in two places consciously at once. The concurrent lives are functionally partitioned—you do not normally feel your simulcarnate selves, any more than one process feels another running on the same machine.
It is not soul-fragmentation in the damaging, dissociative sense, nor is it "walk-in" or possession phenomena, where a different consciousness occupies an existing body. Nor should it be confused with the popular new-age notion of "parallel lives" experienced as a seamless simultaneous panorama; as a general rule, what the experiencer's lower mind can access of its other threads is, at best, intuition, resonance, or fragmentary recall.
It is also not a claim that the Monad multitasks. In the CTM the Monad is the non-executing ground; it does not run lives. Simulcarnation is a Causal-tier (Oversoul) operation, not a Monadic one. Keeping that distinction clear prevents the common conflation of the Monad with the Oversoul that muddles much reincarnation writing.
Within the Consciousness Transition Model, the Oversoul / Disk (the Causal body) functions as a hypervisory state manager: an architect-level intelligence that emanates, configures, and integrates personality-instances without being any of them. Simulcarnation is what this looks like when two or more of those instances are "live" at the same time.
Each incarnation is a child node—a sandboxed runtime bound to a biological device—connected to its Causal parent through the narrow bandwidth of the antahkarana (the subtle connecting channel, or "silver cord," that links a personality to its higher self in Theosophical and Vedantic terms). The Oversoul allocates a portion of its energy to each thread, synchronises data between them (surfacing occasionally as intuition, déjà vu, or genius flashes), and reintegrates their distilled experience upon each thread's "shutdown" (death). Because the Oversoul can run many such threads across time, its experiential "harvest" compounds far faster than a linear one-life-at-a-time model would allow (as seen, for example, in Steiner or Blavatsky).
This also dissolves the old objection that a fast-growing population would need an ever-larger supply of souls. The popular version of that objection, that more people are alive today than have ever lived, rests on a myth: the Population Reference Bureau estimates that roughly 117 billion humans have ever been born, against about 8 billion now living. More to the point, the CTM does not draw incarnations one by one from a fixed queue of souls; they are emanated concurrently, and multiply, from a comparatively small number of Oversouls. Simulcarnation is the concurrency model of reincarnation: the Oversoul is not a single sequential player but a multithreaded runtime, sustaining several lives at once and integrating them all.
Two further CTM threads apply here. First, simulcarnation is coordinated at the mid-level of soul-group dynamics: concurrent lives are not emanated in isolation but planned alongside the soul group, so that threads meant to intersect are timed and placed to run together. Second, the glimpses a personality catches of its other threads—intuition, déjà vu, unexplained affinities—are real perceptions, but they are easily misidentified. Under the Misidentification Principle the experience is valid while the label is not: such a glimpse is readily mistaken for a past-life memory or a "soul-mate" recognition when it is in fact resonance between concurrent threads of the same Oversoul.
The idea long predates the terminology. The Seth material (via medium Jane Roberts) is explicit that the larger self lives "simultaneous" or "reincarnational" lives across time rather than strictly in sequence (see Seth Speaks). Robert Monroe and Bruce Moen describe the Disk / I-There as a closely unified collective field of many personality-members, some incarnate at once. Jurgen Ziewe reported encountering, out of body, living reincarnations of his own deceased father and grandfather—parallel selves active concurrently. Michael Newton's life-between-lives corpus documents souls incarnating into two or three bodies at the same time. Theosophy is more conservative here, tending to describe one personality per cycle, though its holographic causal-body model leaves room for the concept. Sources: the Seth material (Jane Roberts, Seth Speaks, 1972); Robert Monroe, Ultimate Journey (1994); Bruce Moen, Voyage to Curiosity's Father; Jurgen Ziewe, Vistas of Infinity; and Michael Newton, Destiny of Souls.
The convergence is not that every tradition teaches simulcarnation outright, but that several independent experiential sources—decades and methods apart—describe a single higher self sustaining more than one concurrent life.

Simulcarnation is the simultaneous incarnation of two or more personalities emanated from the same Oversoul—several concurrent lives “across time” sustained by one higher self, rather than a single soul living one life at a time.
In the CTM, yes. Only part of the Oversoul's energy goes into any one body, so it can animate multiple bodies concurrently—sometimes in overlapping eras or different experiential "dimensions." Michael Newton's regression subjects reported the same.
Normally no. The concurrent lives are functionally partitioned. What surfaces is usually indirect—intuition, déjà vu, unexplained affinities, or fragmentary recall—rather than a direct, simultaneous experience of the other selves.
The CTM treats it as a Causal-tier operation: the Oversoul (Disk) acts as a hypervisory state manager running multiple personality "threads" like multithreaded processes, synchronising and integrating them without directly executing them. It is not a Monadic function—the Monad is the non-executing ground.
It overlaps with "parallel" or "simultaneous lives" as used by Seth and others, but the CTM frames it precisely—concurrent, partitioned incarnations coordinated by the Causal body—rather than as a seamless simultaneous panorama the personality can simply access.
