Open up the spiritual anatomy. The physical body (Honam in Akan, the visible-tangible flesh-and-bone you can touch) is the outermost layer. Inside that, occupying the same space but at a different ontological register, is the spirit-body — Sahu in Kemetic, Tsumtsum or Sunsum in Akan. The spirit-body is shaped like the physical body. It is bound to the physical body during life. It travels with the physical body's general configuration. When you see your spirit-body in a dream or in a near-death experience, it looks like you.
Inside the spirit-body, in the head region, sits another structure — the spirit-house containing the Ka, the Okra, the divinity-in-your-head. The spirit-body is the shrine that houses this innermost divinity. The architecture is layered: physical body (outside), spirit-body (middle), Okra-house-with-Ka inside the head of the spirit-body (inside).1
When you die, the spirit-body separates from the physical body. The Ka in the head region travels with the spirit-body, not with the corpse. The physical body decays; the spirit-body persists; the Ka remains housed in the spirit-body until specific architectural events shift it.
The Sahu (Kemetic) / Sunsum-Tsumtsum (Akan) architectural-name refers to the spirit-body, distinguished from:
The Sahu-Sunsum is operationally distinct from each of these. It is the body-shaped spirit-substance that occupies the same space as the physical body during life. It is the operational substrate within which the Ka resides — the Ka's "shrine-house" in the head region is inside the Sahu-Sunsum spirit-body.2
The architectural hierarchy:
During life, all three layers are co-located. The physical body holds the spirit-body; the spirit-body holds the spirit-house-with-Ka. Practices that develop spirit-body awareness (Suhumesum meditation, dream-state practice, subtle-perception cultivation) work with the spirit-body layer specifically.
At death, the physical body and the spirit-body separate. The spirit-body, carrying the spirit-house-with-Ka, departs the physical body. For approximately 40 days (six-week cycle in Akan tradition), the spirit-body lingers near the physical body and the family-home, going through adjustment to its new condition (see Forty-Day Post-Death Vigil). After that period, the spirit-body journeys to the ancestral realm (Asamando) for its longer-term residence.
The architectural specification has operational implications for practice:
Spirit-perception capacity targets the spirit-body layer. When practitioners with developed spirit-perception "see" deceased relatives, they are perceiving the spirit-body (Sahu-Sunsum), not the Ka directly. The Ka is housed inside the spirit-body's head and is not directly perceivable from outside even when the spirit-body itself is perceivable.
Dream-state operates through the spirit-body. When you dream, your spirit-body engages other spirits. The physical body lies still; the spirit-body is active in spirit-realm interactions. This is one of the operational instances of spirit-body activity that doesn't require death-separation (see Dream-State as Afterdeath-State).3
Possession during ritual works through the spirit-body. When an ancestor possesses a practitioner during ritual dance/drum/song, the visiting spirit-body temporarily occupies the practitioner's body alongside the practitioner's own spirit-body. The practitioner's spirit-body retreats temporarily; the visiting spirit-body uses the practitioner's physical body for the duration of the possession.
The 40-day post-death period engages the spirit-body specifically. Family ritual practices during this period — graveside offerings, prayers, libation at the home — are addressed to the spirit-body that is lingering near the physical body and the family. The Ka is inside the spirit-body during this period and receives the family's offerings through the spirit-body's mediation.
This page sits at the architectural foundation of the broader Akan-Kemetic spiritual anatomy:
Akan Spiritual Anatomy: Honam / Sunsum / Kra is the foundational personhood architecture; this page specifies the Sunsum-as-spirit-body layer with its Sahu cross-tradition identification.
Samain / Osamai — Deceased-Spirit Electromagnetic-Form documents what happens to the spirit-body after death.
Forty-Day Post-Death Vigil documents the 40-day period the spirit-body lingers.
Dream-State as Afterdeath-State documents the dream-state spirit-body activity.
Abatuma — Melanin-Body documents the third body-layer specification in some Akan-tradition variants.
Okra-Complex Cerebrum-Cerebellum Four-Shrine Neuroanatomy specifies the head-region within the spirit-body where the Okra is housed.
A practitioner is doing Suhumesum meditation practice. They sit, close their eyes, settle their attention into the body. The physical-body-attention is the outermost layer — sensations of weight, temperature, pulse.
They sustain the meditation. The attention drops inside the physical body. They start to feel the spirit-body — a body-shaped subtle-energy presence that coincides with the physical body but has different qualities. The spirit-body feels more fluid, more vibrationally-active, lighter. The practitioner has now moved attention from the outermost layer (physical body) to the middle layer (spirit-body).
They sustain the practice further. The attention concentrates in the head region of the spirit-body. They start to notice the spirit-house — a specific structural region within the spirit-body's head where the Ka resides. The Ka itself is perceivable as the colored radiant disc (Bena's red, or whichever day-deity-disc applies). The practitioner has now reached the innermost layer.
This is the architecture made operational through meditation. The three layers are not just theoretical specifications — they are actually perceivable in sustained practice. The Suhumesum meditation works by guiding attention progressively through the layers from outside to inside, ending with direct contact with the Ka in the spirit-house in the head of the spirit-body inside the physical body.
The practitioner who has done this practice repeatedly knows the three layers experientially. They can move attention between layers deliberately. They can engage practice at whichever layer is operationally relevant for the situation. The architectural specification becomes a navigation-tool for spiritual practice rather than just a theoretical framework.
The three-layer (physical body / spirit body / spirit-house-with-Ka) architecture is consistent with mainstream Akan ethnography and with Kemetic primary-source documentation. The Sahu / Sunsum-Tsumtsum identification of the spirit-body layer is documented across the Akan-Kemetic continuity framework.
The mainstream Egyptological treatment of Sahu generally identifies it as the "spiritual body" or "glorified body" — the body the deceased operates in after death. The Akan-tradition's specification of Sahu as continuously-present during life (as the spirit-body underneath the physical body) extends this somewhat. The extension is internally consistent with the broader Akan-Kemetic architecture.
Open question: the relationship between the Sahu-Sunsum spirit-body and the Ba (divine-life-spirit). The Ba is documented elsewhere as a Kemetic personhood-component. Does the Ba operate within the Sahu, alongside it, or as a different layer entirely? The source-material treats them as related but operationally distinct without fully specifying the architectural relationship.
You read the mainstream Egyptological treatment of Sahu. The Sahu is described as the spiritual body of the deceased, the body in which the deceased exists in the afterlife. Standard Egyptological frameworks focus on the post-death context.
You read Odwirafo's account in the Okra Okraa Course. The Sahu (Sunsum-Tsumtsum in Akan) is continuously present during life, as the spirit-body underneath the physical body. The post-death context is one operational mode; the during-life context is the other.
Both frames agree on the Sahu as spirit-body specifically — a body-shaped spirit-substance. They part company on the temporal scope of operational presence. The Egyptological frame emphasizes post-death context; the Akan-tradition extends to continuous-presence-during-life as well.
The post-death-emphasis in Egyptological treatment may be a function of the primary-source corpus available — funerary-text material is what survives most extensively from ancient Kemet, so Egyptology has more documentation of post-death-context Sahu than of during-life-context Sahu. The Akan-tradition's continuous-presence emphasis may reflect operational practice that uses the spirit-body during life as well as at death; this operational continuity may have been part of the original tradition but is less visible in the surviving Kemetic primary-source corpus.
You read about Tibetan Bon and Buddhist tradition's vajra body — a subtle-energetic body that coexists with the physical body and that is the substrate for various advanced contemplative practices. The vajra-body has specific energy-channels (nadi), wind-currents (lung), and bindu-points that practitioners develop through specific practices. The structural architecture is parallel to the Akan-Kemetic Sahu-spirit-body — a subtle-body coexisting with the physical body, the substrate for advanced practice.
Eastern-spirituality: Sukshma Sharira / Vajra Body — Subtle-Body Architecture — A Tibetan dzogchen practitioner spends years developing perception of the vajra-body — the subtle-energetic body with its specific nadi channels, lung wind-currents, and bindu-points that coexists with the physical body and is the substrate for advanced contemplative practice. A Vedic practitioner does parallel work with the sukshma sharira (subtle body). Both traditions develop extensive subtle-body architectures with specific operational practices. The Akan Sahu / Tsumtsum spirit-body parallels these architectures structurally — body-shaped subtle-substance coexisting with the physical body, the substrate for spiritual practice. The traditions diverge in specific operational details but converge on the general architecture. Subtle-body architectures appear across multiple unrelated traditions. The cross-tradition convergence supports the architecture as operationally real beyond cultural-construction explanations. The specific operational practices for engaging the subtle-body differ tradition to tradition, but the underlying architecture (body-shaped subtle-substance with specific perceivable features) recurs.
Psychology: Proprioception and Body-Schema vs Subtle-Body Perception — A neuropsychologist studies the body schema — the internal mental representation of the body that allows proprioception, body-awareness, and motor-coordination. The body-schema is operationally real but does not match physical-body perfectly — it can be expanded (tool-use), distorted (phantom limbs), or otherwise reshaped through perception. The Akan-tradition's spirit-body description has structural similarities to body-schema — a body-shaped non-physical representation that the practitioner perceives and operates through. Contemporary psychology and neuroscience have frameworks for body-shaped non-physical representations that the Akan-tradition spirit-body specification can be partially mapped onto. The two frames are not identical — body-schema is treated as neurological-cognitive representation; spirit-body is treated as ontologically-real subtle-substance — but the operational similarities are striking. A practitioner familiar with both frames might find the cross-frame translation productive for understanding what they are perceiving in spirit-body practice.
The Sharpest Implication
If the spirit-body (Sahu / Sunsum-Tsumtsum) is operationally present during life as a body-shaped subtle-substance coexisting with the physical body, then most contemporary practitioners are operating on only one layer of the three-layer architecture they actually inhabit. The physical-body layer gets attention through ordinary embodied experience. The spirit-body layer is largely outside the contemporary attentional repertoire — practitioners who don't do specific spirit-body practices don't perceive it and don't operate through it deliberately. The innermost Ka-layer (the personal divinity in the head region) is even further outside contemporary attention. The standard contemporary experience of "being a person" is operating with only one of three available perceptual-and-operational layers. The other two layers are available — the tradition documents practices for developing perception of them — but they require deliberate cultivation. Most practitioners go their entire lives without ever directly perceiving their spirit-body or their Ka, even though both are continuously present. The architectural specification implies a much richer operational human existence than contemporary practice typically engages with.
