This is a free sample from Leaning Into Our Nature: The Clinician’s Workbook, aligned to The LION Model, Version 4.8. Copyright © 2026 by Justin M. Eastland. All rights reserved. The workbook is a companion to Leaning Into Our Nature: A Modern Return to Ancestral Values and to The LION Model (v4.8), the structural specification beneath the book. It is intended for use by licensed mental health clinicians, clinicians in training under supervision, and clinically-adjacent professionals integrating the framework into their existing practice.
The full workbook contains five parts: the model for clinicians (Sections 1.1 to 1.15), eight case-conceptualization worksheets, eleven session-ready protocols, six assessment tools, and the clinician’s own work, plus four appendices. This sample includes the front matter and Section 1.1. Cross-references to other sections point to the full workbook.
What the LION Model Is, and Isn’t
The LION Model is not a therapeutic modality, and this workbook does not ask you to set aside the methods you already practice. The model is a framework you operate those modalities inside of. It is the organizing layer, the structure that lets you read a presenting case, locate where the work belongs, and connect interventions that would otherwise stay separate into a single coherent account of what is happening and what the work requires.
The treatment is still yours. CBT, EFT, psychodynamic, somatic, attachment, and family-systems work, the evidence-based traditions you were trained in, do what they do. The model does not replace them or compete with them. It gives them a shared frame: a common way to name what each piece of the work is for, where a case is failing, and how the separate threads connect. Used this way, the model is connective tissue, not a rival.
This is also the honest answer to the question a careful clinician asks first: where is the evidence? The model is not offered as an empirically validated treatment, and it should not be evaluated as one. Its claim is to clinical utility and coherent organization. It helps you see a case more clearly and integrate your work more effectively; the outcomes still come from the validated methods operating within it. It is a working structure, provisional, revised as it meets more cases, not a finished science. Hold it as you would any formulation lens: useful to the degree that it organizes the work and earns its place in the room, and no further.
A Note on Scope
This workbook does not constitute a therapeutic modality, a certification, or a standard of care. The model does not perform capacity restoration, the rebuilding of capacity that trauma or attachment has depleted below the threshold where the lean is available at all; that work belongs to the depth-clinical traditions the clinician already practices. The model operates downstream of that restoration, at the per-act point of leaning, though, as Part 1 develops, the lean itself raises capacity above threshold as a side effect. Integration with your existing training, supervision, ethical obligations, and scope of practice is required. Review the model’s non-application categories before using this workbook with patients.
If a patient is in acute crisis, the framework can wait. Their safety can’t.
How to Use This Workbook
This workbook has three operating modes, used together.
Mode 1: Learn the model. Work through Part 1 sequentially. The model is closed and cumulative; each component presupposes the prior components. Skimming produces partial readings that won’t operate diagnostically. Plan on roughly the equivalent of one CE unit per major section if you’re reading carefully, doing the reflection prompts, and walking your own architecture through the diagnostics before bringing them to patients. If you need diagnostic precision on a specific presentation before you have read all of Part 1, Appendix A gives reading paths through the parent book by presenting problem.
Mode 2: Use it in session. Parts 2, 3, and 4 are organized for direct clinical use, and they are three different kinds of tool. Part 2 holds Worksheets: progressive case-conceptualization sheets you complete to build a working formulation, from a first snapshot (2.1) to a full case formulation (2.8). Part 3 holds Protocols: session-ready interventions, each with its indication, preparation, in-session language, and failure modes. Part 4 holds Instruments: quick, repeatable screens and decision aids that put the diagnostic questions into structured form. As a rule of thumb, screen with the Part 4 instruments, deepen with the Part 2 worksheets, and intervene with the Part 3 protocols. Each tool names its source in the parent book or the model, the presentation it is calibrated to, suggested language, and the most common failure modes, and is designed to be opened on a tablet, projected, or printed. Nothing here substitutes for clinical judgment; everything is offered as a structural scaffold your judgment can build on.
Mode 3: Train yourself first. The model asks something specific of the clinician that most modalities do not. The clinical methodology requires the clinician to anchor the polarity tension from assertive neutral, and assertive neutrality is impossible for a clinician whose own roles are still live. A clinician whose configurations activate in response to the operator’s becomes a second pole in a toxic balance with the patient. Part 5 is the clinician’s own work, not as a personal-growth exercise, but as the structural precondition for occupying the anchor position. Patients reliably detect when the clinician is operating outside the framework while teaching it.
The Central Discipline
The model’s single most consequential ethical discipline, in clinical practice, is this: the model governs the operator. Every operator running the model governs only their own system.
Patients will press for permission to apply the model to their partners, their parents, their children, their colleagues. Clinicians will press for permission to direct the patient’s correction. The discipline holds in both directions. Diagnosis is information when offered; it becomes direction when offered with the expectation that it will produce specific behavior in the system being diagnosed. The architecture being corrected is always the one in the room, and the correction is always that operator’s own work.
Part 1: The Model for Clinicians
The LION Model (v4.8), condensed for clinical use, with notes on integration
1.1 The Six Components, at a Glance
Sources: parent book, Chapter 1; LION Model 4.8, Framework and System Map.
The model is a closed behavioral operating system. It governs how behavior organizes, expresses, distorts, stabilizes, and corrects under pressure. It has no off state; it is always running. Every moment is alignment or distortion; every action reinforces direction; every repetition builds pattern. The system changes only through behavior; it does not respond to what the operator thinks, feels, or intends. It responds to behavior. Always.
The model operates through six components. These are not modules. Every behavioral event runs through all six, in order.
| Component | What it is, in one sentence |
|---|---|
| Pressure | The input force. It does not create dysfunction; it reveals it. The system does not fail in calm conditions. Pressure is the diagnostic instrument of the system at scale. |
| Capacity | What is available under pressure, at three levels: baseline (long-term systemic state), available (current usable state), and domain (strength within a specific domain). When pressure exceeds available capacity, the system breaks, not bends. |
| Polarity | The full expression of congruence in a relationship: frame-holding (masculine) and signal-bringing (feminine) functions in generative tension. Polarity also orients each function on the threshold of behavior: masculine pulls toward the aggressive side, feminine toward the passive side. |
| Sequence | The four-step path every decision travels, in order, every time: Perception → Conscience → Execution → Connection. Distortion enters at one step and compounds forward; correction travels the same path. |
| Domains | The four locations of failure (Mental, Spiritual, Physical, Relational), each with a congruent state, an incongruent state, and an axis of movement between them. The system fails first at the weakest domain, not the most visible one. |
| Identity | The stabilized output of the system, built through repetition under pressure. Identity is always downstream of behavior. It follows the pattern. It never leads it. |
The two relationships, and why intent is not evidence
Behavior expresses through exactly two relationships: the operator’s relationship with themselves, and the operator’s relationship with others. There is no third venue. A skipped workout is self-to-self behavior; an argument with a partner is self-to-other. Both are diagnostic, because the breakdown, wherever it originates in the architecture, becomes visible as behavior in one or both of these channels.
Intent is not evidence. Intent is internal to the operator and is never seen; what others react to is the behavior, accurately, because the behavior is the only thing that arrived. This is why the model’s first application is always to the operator’s own architecture: the operator is the only system about which they have full information. Any diagnosis of another operator is necessarily a diagnosis from behavior alone.
What the model does, and does not do
The Division of Labor. The model does not perform capacity restoration. Restoration, rebuilding capacity that trauma or attachment has depleted below the threshold where the lean is available at all, is done by the depth-clinical traditions: CBT in the mental domain, polyvagal and somatic-experiencing work in the physical and autonomic domain, attachment-based and family-systems work in the relational domain, trauma-specific modalities wherever the trauma has depleted the system.
What the model does do, above that threshold: it increases capacity as a side effect of the lean. This is not an exception bolted onto a capacity-neutral model; it is an inherent byproduct of the practice the model already prescribes. Two mechanisms: acceptance (the operator who accepts alignment with their nature stops spending capacity on the internal friction of resisting their own function, and that freed capacity becomes available) and resilience (aligned behavior executed against the pull of the distortion is the precise event that builds resilience). The two compound: each aligned act under pressure is both the expression of capacity and the generation of more of it.
So the division is not capacity-work-elsewhere / behavior-here. It is: restoration below threshold is the modalities’ work; everything above threshold, the per-act lean and the capacity it generates, is the model’s. The model operates downstream of restoration and positions you as an integrative clinician, not a pure-framework practitioner. For the operator still depleted below threshold, the lean isn’t yet available, so its capacity-producing side effect isn’t either. Restoration comes first.
Clinician Note
From the LION Model 4.8: “The model does not rebuild depleted capacity. It does increase capacity, inherently, for every operator for whom the lean is performable.” The flat claim that it does not rebuild capacity, the model notes, “is true in a narrow sense and false in a broad one.”
Translation for use: the model gives you a structural account of which modality each patient needs, in which domain, and in what order, and then names the per-act behavioral work that the restored capacity is for, work that itself generates more capacity. This puts it in productive tension with insight-oriented frameworks without being in opposition to them: cognition is a step in the sequence, not the lever. Only behavior corrects behavior, and the same behavior, sustained, builds the capacity to keep performing it.

Where This Goes Next
Section 1.2 takes up Pain, Peace, and Avoidant Peace, the two signals the system runs on and the counterfeit that mutes them. Section 1.3 covers Pressure and Capacity, including the treatment-sequencing rule the model gives you: gate every behavioral assignment through the capacity question first.
