From Altered States to Fundamental Peace: Taxonomies of Consciousness, Psychedelics and Hypnosis Through the Lens of the Yoga Vāsiṣṭha

Bottom line: Repeated intense mystical experiences may not lead to greater relief, suggesting that the intensity of the initial experience may be more important than the frequency.

A researcher is about to give someone a dose of psilocybin, convinced it will change their life. But what if the real transformation doesn’t come from the drug itself, but from how the person responds to the experience? That’s the question at the heart of the 2026 Annual Conference of the Society for Clinical and Experimental Hypnosis (SCEH), where scientists and philosophers are rethinking everything about altered states of consciousness.

The answer, it turns out, may lie in an ancient Indian text and a modern psychological model that together suggest the key to lasting change isn’t the state itself—but the stance the experiencer takes toward it.

The Limits of Trigger-Based Labels

For decades, altered states of consciousness have been categorized by what causes them: psychedelics, hypnosis, meditation, or even trauma. But the 2026 SCEH conference challenged this approach, arguing that the same kind of experience—like a feeling of unity, detachment, or altered identity—can arise from multiple triggers.

This new perspective is based on a consensus taxonomy developed by Cardeña, which focuses on the feel of the state, not the method used to get there. Unity, for example, is the experience of merging with the world or a higher self, no matter if it comes from a psychedelic, a hypnotic suggestion, or a deep meditation.

The conference’s findings suggest that trigger-based labels are too limiting. If we can identify the shared features of these states, we might finally move beyond vague categories like “mystical experience” and ask more precise questions about what actually causes transformation.

The Intensity of Mystical States and Their Limits

One of the most striking findings from the conference came from a meta-analysis of psilocybin-assisted psychotherapy for anxiety, conducted by Hood and Elkins. They found that the intensity of a mystical experience at the first dose correlated strongly with the benefit the patient received. But here’s the twist: repeated mystical states did not bring proportionally more relief.

This is a sobering realization. It suggests that the power of a mystical experience isn’t in how often it occurs, but in its quality and context. If a person has a powerful, emotionally resonant experience, they might gain more from it than someone who has the same experience multiple times but doesn’t internalize it as deeply.

Even more intriguing was the finding that hypnosis can occasion mystical states without showing comparable clinical change. That’s a puzzle. If hypnosis can produce the same kind of experience as psychedelics, why isn’t it as effective in treating anxiety or depression?

The answer may lie in the stance the person takes toward the state. That’s where the Yoga Vāsiṣṭha comes in.

The Yoga Vāsiṣṭha and the Seven Stages of Knowledge

The Yoga Vāsiṣṭha, an ancient Sanskrit text, offers a unique perspective on altered states of consciousness. It describes seven stages of knowledge (jñāna-bhūmikā), each representing a deeper level of understanding and integration. These stages range from the initial experience of unity to the final state of complete liberation from the illusion of separation.

The conference argued that the missing variable in psychedelic and hypnosis research is the experiencer’s stance toward the state. In other words, how they interpret and relate to the experience matters more than the experience itself. If someone approaches a mystical state with curiosity and openness, they’re more likely to integrate it into their daily life. But if they’re fearful or dismissive, the experience may remain a fleeting moment without lasting impact.

This idea is operationalized in the Fundamental Peace model, which breaks down the experience into four components: presence, acceptance, non-attachment, and integration. The FP20 scale, developed by the author of the conference paper, measures these components and provides a way to track how a person’s stance toward an altered state evolves over time.

A Network Account: From State to Change

The conference paper also proposed a network account of how altered states lead to lasting change. This model links the default mode network (associated with self-referential thought), the salience network (which detects important stimuli), and the executive control network (responsible for decision-making and focus).

According to this model, a mystical experience might initially activate the default mode network, creating a sense of unity or detachment from the self. But for lasting change to occur, the person must engage the executive control network to reflect on the experience and integrate it into their worldview. The salience network helps them recognize the significance of the experience and prioritize it in their daily life.

This network account suggests that the path from an extraordinary state to lasting change is not automatic. It requires a shift in how the person engages with the state—what the Yoga Vāsiṣṭha calls a change in stance.

Frequently Asked Questions

Q: Does this mean psychedelics are just as effective as hypnosis?
A: Not necessarily. The study shows that both can occasion mystical states, but the stance the person takes toward the experience may determine the outcome. Hypnosis, for example, may be more effective in certain contexts because it allows for greater control over the experience.

Q: How does the Yoga Vāsiṣṭha relate to modern psychology?
A: The Yoga Vāsiṣṭha provides a framework for understanding altered states of consciousness as stages of knowledge. It suggests that the path to transformation is not just about the state itself, but about how the person relates to it—what the authors call the “stance.”

Q: Can the FP20 scale be used in clinical settings?
A: The FP20 scale is still in development, but it offers a way to measure the four components of Fundamental Peace. It could potentially be used in clinical settings to track how patients integrate their experiences and shift their stance toward altered states.

Q: Why is the stance toward the state so important?
A: Because how you interpret and relate to an experience can determine whether it becomes a part of your worldview. If you approach a mystical state with curiosity and openness, you’re more likely to integrate it into your daily life and see it as a meaningful shift.

Q: What’s next for this research?
A: The authors propose a four-layer model (Context–State–Stance–Trait) as a research agenda. This model could help guide future studies on how altered states lead to lasting change, with hypnosis serving as an experimental control for psychedelic research.
