COURSE

The Dark Side Of Meditation

With Tomer Weiss

This course offers a deep and compassionate exploration into the lesser-known challenges that can arise during meditation practice. While meditation is often portrayed as a path to peace, clarity, and emotional well-being, many practitioners encounter difficult, confusing, or even distressing experiences along the way. These are not signs of failure—but signals that something deeper is unfolding. Drawing from ancient spiritual traditions, contemporary neuroscience, and real-world case studies, this course sheds light on the psychological, emotional, somatic, and spiritual effects of meditation that are often overlooked in mainstream teachings. Topics include meditation-induced depression, anxiety, depersonalization, sensory disturbances, spiritual crises, and more. Rather than discouraging meditation, the course aims to empower practitioners, teachers, and mental health professionals with the tools to recognize, understand, and respond to these experiences with wisdom and care. Each session includes reflection prompts to help integrate the material and apply it to personal or professional practice. Whether you’re a seasoned meditator, a teacher, or a newcomer, this course invites you to engage with meditation in a more nuanced and informed way—one that honors both its light and its shadow. Disclaimer: This course includes sensitive content related to trauma, depression, anxiety, psychological distress, emotional dysregulation, spiritual crisis, dissociation, and adverse effects of meditation practices, and may not be suitable for individuals currently in acute mental health crisis.

Lesson 1

Beyond The Bliss – Why We Must Talk About The Dark Side

This opening session sets the stage for a deeper and more honest understanding of meditation—not as a guaranteed path to peace, but as a powerful practice that can reveal our light and our shadow. We explore why adverse effects are often hidden, how pluralistic ignorance sustains silence, and why naming these difficulties is a vital step toward safer, wiser practice.

Lesson 2

The Many Faces Of Meditation

In this class we will explore the wide range of meditation techniques and the diverse emotional, cognitive, and physical effects they can induce— we will look not only to the beneficial ones but also to the adverse effects.

Lesson 3

Warnings From The Past, Problems Of The Present

Ancient meditation traditions did not shy away from warning practitioners about possible dangers—ranging from energetic imbalances to existential fear. This session explores how those traditional frameworks and safeguards have been stripped away in modern, secularized mindfulness and self-help contexts, leaving many practitioners unprepared for the challenges that may arise.

Lesson 4

When Meditation Brings Sadness – Depression On The Cushion

Depression during meditation is more common than most expect. This session explains how heightened introspection, rumination, and unprocessed trauma can arise during stillness, triggering feelings of hopelessness, sadness, and emotional shutdown. You’ll learn why this happens, what neural networks are involved, and how to work with these states compassionately and safely.

read more

Lesson 5

Fear In Stillness – Meditation And Anxiety

Meditation can heighten awareness of internal sensations and unresolved fears, sometimes triggering anxiety or even panic attacks. This session explores how increased sensitivity, somatosensory amplification, and introspective spirals can create overwhelming fear—even in the absence of external danger—and offers tools to recognize and gently regulate those responses.

read more

Lesson 6

The Fire Within – Anger In Meditation

Far from always producing peace, meditation can surface buried rage, frustration, or unresolved trauma. This session explains how suppressed anger can erupt during practice as emotion, imagery, or physical agitation, and how the nervous system’s fight response may reactivate in deep introspection. You'll also learn how to hold space for anger without judgment.

Lesson 7

When Emotions Fall Silent – Emotional Flattening And Detachment

While emotional regulation is often a goal of meditation, some practitioners experience the opposite of emotional richness: numbness, disconnection, or an inability to feel. This class explores how overactivation of regulation mechanisms, trauma-related freeze responses, and prolonged detachment practices can lead to emotional flattening or alexithymia.

Lesson 8

Escaping Through Spirituality – The Trap Of Spiritual Bypassing

Spiritual bypassing happens when meditation is used to avoid, rather than engage with, emotional wounds or unresolved psychological issues. This session explores how even sincere practice can mask pain with spiritual ideas—like detachment, compassion, or “letting go”—in ways that disconnect us from reality. It also looks at the long-term costs of bypassing for mental health, relationships, and growth.

read more

Lesson 9

Clouded Mind – Meditation And Cognitive Impairments

Although meditation is often praised for enhancing focus and clarity, some practitioners experience cognitive decline—difficulty concentrating, memory lapses, or decision paralysis. This session explores how long retreats, dissociation, or overuse of inward-focused techniques can impact executive functioning and why self-awareness and pacing are critical for preventing long-term effects.

read more

Lesson 10

Disconnected From The World – Social And Motivational Impairments

This session explores how meditation, especially in its intensive forms, can reduce social interest, disrupt motivation, or dampen emotional engagement with others. Whether it's framed as detachment or interpreted as spiritual maturity, these symptoms can sometimes reflect subtle withdrawal or emotional shutdown. We'll explore how to distinguish true equanimity from quiet disengagement.

Lesson 11

Strange Perceptions – Sensory And Spatial Distortions

Meditation can alter sensory experience—sometimes beautifully, sometimes unsettlingly. This session examines experiences like visual distortions, time dilation, bodily disintegration, and perceptual hypersensitivity. While some are interpreted as mystical openings, others can be disorienting or frightening. You'll learn why they happen and how to manage them safely and skillfully.

Lesson 12

The Body Speaks – Somatic Phenomena In Meditation

Meditation often stirs not just the mind but the body. Practitioners may experience unexplained aches, twitches, nausea, heat, tremors, or energetic surges. These phenomena can be healing or destabilizing, depending on the context and individual. This session explores how the nervous system, stored trauma, and energy systems interact with stillness and how to approach somatic experiences with care.

read more

Lesson 13

Troubled Sleep – Meditation And Sleep Disturbances

While many use meditation to help sleep, certain techniques—especially when practiced intensively or late in the day—can lead to sleep disturbances, vivid dreams, nightmares, or nighttime arousal. This session examines the neurophysiology of meditation-induced insomnia and dream intensification, and offers practical strategies for restoring balance between rest and practice.

read more

Lesson 14

Dissolving The Self – Dissociation And Loss Of Agency

Deep meditative states can dissolve the ordinary sense of self—but for some, this goes too far. This session explores the line between insight into non-self and dissociation, including symptoms like feeling unreal, detached from one’s body, or as if life is happening automatically. We’ll examine causes, risk factors, and how to recognize when loss of agency becomes a sign of disintegration.

read more

Lesson 15

Belief Gone Strange – Psychosis And Unreal Thoughts

In rare cases, meditation can open the door to psychosis-like symptoms—hallucinations, delusions, or beliefs disconnected from consensual reality. This session explores how meditation can mimic or trigger psychiatric episodes, why certain techniques or contexts raise the risk, and how to distinguish mystical insight from a psychological rupture that needs immediate attention and support.

read more

Lesson 16

Breakdown Or Breakthrough? – Spiritual Emergencies

Spiritual emergencies are powerful, destabilizing experiences that resemble psychological breakdowns but often carry a deep sense of meaning or transformation. This session explores how sudden awakenings can overwhelm the nervous system, challenge identity, or disrupt daily life. It also offers ways to support integration, including grounding practices and trauma-informed guidance.

read more

Lesson 17

The Sacred Darkness – Traditional Frameworks For The Dark Night

Many traditions—including Christian mysticism and Theravāda Buddhism—have long described dark phases of practice as necessary passages. These “Dark Nights” involve despair, doubt, emotional numbness, and existential crisis. This session explores classical models of these experiences, distinguishing between sacred difficulty and pathology, and how to walk through them with support and insight.

read more

Lesson 18

Who Is At Risk? – Understanding Vulnerability In Practice

Not all practitioners are equally vulnerable to meditation-related challenges. This session explores key risk factors—such as trauma history, neurodivergence, psychological sensitivity, and retreat intensity—and how they interact with specific techniques. You'll learn how to assess readiness, tailor practices wisely, and recognize signs that someone may need extra care or support.

read more

Lesson 19

Holding With Care – Mitigation And Support Strategies

This session focuses on how to prevent and respond to adverse meditation experiences through thoughtful design, trauma-informed practices, and accessible support. Whether you’re a teacher or practitioner, you’ll learn practical tools for creating a safer environment—including pacing, grounding, integration techniques, informed consent, and when to pause or seek external help.

Lesson 20

Teaching With Integrity – Ethics And Responsibility In Guiding Practice

Teaching meditation carries deep ethical responsibility. This session explores the need for boundaries, trauma awareness, and transparency when guiding others. It outlines key elements of responsible teaching—like referral networks, ethical communication, safety planning, and knowing the limits of your role—so that practitioners are empowered, not harmed, by your guidance.

read more

Lesson 21

Integration And Continuity – Walking Forward With Wisdom

The final session brings together everything explored in the course. It focuses on integration—how to digest difficult experiences, build long-term resilience, and cultivate a practice that is honest, embodied, and sustainable.
