Have you ever noticed a moment where your suffering came not from what was happening, but from your expectations and resistance? What shifted when you saw that?

May this work benefit many 🙏

My deep gratitude to first author Andrea Grabovac, and co-authors Nickolas Grabovac, Winson Yang, Molly Haggerty, Malcolm Wright, and the contemplative traditions that help inform our research.

-- By formalizing potentially challenging stages like "Foundational Instability," we provide a clinical lens for understanding destabilizing altered states of consciousness, framing them not as pathology, but as developmentally appropriate steps toward deep psychological growth

-- We differentiate fleeting "momentary insights," brief shifts in how reality is perceived, from "integrated insights," which are more durable, baseline shifts in cognition, perception, affect, and behavior

-- We outline 8 distinct stages mapping phenomenology from the "Initial Decomposition" of sensory experience to profound equanimity, and ultimately the “Momentary Cessation of Consciousness”

What emerged from this project is a framework that, for the first time, maps the arc of advanced insight practice in an empirically testable format. This work makes several key contributions we believe will be of broad interest to researchers, clinicians, and practitioners:

-- Incongruence: Recognizing the painful mismatch between our brain's rigid expectations for stability and control, and the fluid, unpredictable nature of reality

-- Self-lessness: Experiencing thoughts, emotions, and actions as arising autonomously, loosening the burden of maintaining a solid, central sense of self

-- Transience: Shifting perception to see seemingly solid, continuous experiences as a rapid, moment-to-moment succession of fleeting phenomena

Drawing on classical Buddhist theory alongside clinical and contemplative practice expertise, we reconceptualize the process of insight development as three testable, psychologically neutral perceptual modes any human can grow:

Here I announce our new preprint: "A Theoretical Framework for Stages of Advanced Insight Meditation.”

In this paper, we introduce the Insight Development Process (IDP).

Advanced Investigative Insight Meditation (AIIM) is a class of practices designed to facilitate this process of insight development. Until now, we have lacked a secular, empirically testable framework to rigorously study this trajectory of insight development.

Yet many traditions describe a profound trajectory of meditative development that involves deconstructing our sense of self, perceiving the transient nature of reality, and ultimately reaching extraordinary meditative endpoints (MEND).

Mainstream science has focused on the stress-reduction benefits of basic mindfulness meditation.

What if the root of suffering isn't what actually happens to us, but a fundamental mismatch between how the world is and how we expect it to be? ⤵️

What role do you think meditation should play in the future of psychedelic-assisted therapy? We'd love to hear your thoughts below.

-- Providing a durable framework for meaningful integration: The meditators reported that psychedelics fostered psychological development, insight-oriented intentions, and a path toward long-term integration and growth that extended well beyond the psychedelic session itself.

Specifically, it allowed practitioners to develop familiarity with altered states, cultivate equanimity to hold space for intensity, and internalize the insight of impermanence to recognize that difficult mind states will pass.

Participants reported that experience navigating challenging experiences during meditation helped them build resilience.

-- Using challenging experiences during meditation as a vital "training ground":

To optimize a pre-psychedelic mindset, participants reported that meditation helped them build openness, positive mood, and cognitive flexibility (the ability to adapt to unpredictable shifts). Lovingkindness meditation was specifically highlighted as a powerful way to set a positive tone.

Three primary themes emerged:
-- Meditation cultivates positive mood and the inner conditions for letting go:

While we explore the potential synergy between contemplative practice and psychedelics, we do not specifically endorse their use in illegal contexts, and we emphasize that they should only be used in safe, supervised, and legal settings.

Their open-ended responses were systematically analyzed using reflexive thematic analysis, a rigorous qualitative research methodology.

We asked them how meditation shapes both preparation (structured activity before a dosing session designed to optimize its impact) and the unfolding of the psychedelic experience itself.
