A mystical experience is a powerful religious experience where a person feels union or oneness with God, the divine, or ultimate reality. William James identified four key characteristics that define mystical experiences: (1) Ineffable — impossible to put into words; language cannot adequately describe it. (2) Noetic — it conveys deep knowledge or insight into the nature of reality that goes beyond normal intellectual understanding. (3) Transient — it's temporary, lasting only a short time. (4) Passive — the person feels taken over by a superior power; they don't control the experience. These experiences are found across all religions and cultures, often transforming the person's life profoundly.
A mystical experience is a specific type of religious experience characterized by a profound sense of union or oneness with the divine, God, or ultimate reality. It's more than just seeing a vision or feeling God's presence—it's an immersive, transcendent experience where the boundaries between self and the divine seem to dissolve.
Mystical experiences are found across all religious traditions—Christianity, Islam (Sufism), Judaism (Kabbalah), Hinduism, Buddhism, and even in secular contexts. People who seek out or have these experiences are often called mystics.
William James (1842-1910) was an American psychologist and philosopher who revolutionized the study of religious experience. His groundbreaking work is The Varieties of Religious Experience (1902), which examined religious experiences from across cultures and traditions.
James approached mystical experiences empirically and sympathetically—he studied actual accounts from people who had these experiences rather than dismissing them as delusions. His goal was not to prove whether these experiences came from God but to understand their nature, characteristics, and effects on human life.
Definition: The mystical experience defies expression—it cannot be adequately described in words. James writes: "The subject of it immediately says that it defies expression, that no adequate report of its contents can be given in words."
Why is it ineffable? Language was designed to describe ordinary sensory experiences. Mystical experiences are fundamentally different from ordinary consciousness. They involve states of awareness that transcend normal conceptual categories. Trying to explain it is like trying to explain the color red to someone born blind.
The Paradox: Mystics still TRY to describe their experiences, but they acknowledge the descriptions are inadequate—like "trying to capture the ocean in a teacup". Many mystical writings use poetry, metaphor, and paradox because literal language fails.
Definition: Despite being ineffable, mystical experiences are felt by the experiencer to be states of knowledge—they provide profound insight into the nature of reality. The term "noetic" comes from Greek noesis, meaning "knowledge" or "perception".
James writes: "Mystical states seem to those who experience them to be also states of knowledge. They are states of insight into depths of truth unplumbed by the discursive intellect. They are illuminations, revelations, full of significance and importance."
What kind of knowledge? Not intellectual or discursive (not reasoned out step-by-step). Direct, immediate perception of truth. Intuitive grasp of reality beyond what reason can achieve. Described as "more real than reality"—the experience feels like ultimate truth has been revealed.
The Authority of Noetic Experience: Mystical experiences carry a "curious sense of authority" that persists long after the experience ends. The person who had the experience feels absolutely certain about what they learned, even if they can't explain it to others.
Definition: Mystical experiences are fleeting and short-lived—they cannot be sustained for long periods. James writes: "Mystical states cannot be sustained for long."
Typical Duration: Most mystical experiences last anywhere from a few minutes to a couple of hours. They rarely extend beyond a day. The peak of the experience is often very brief—mere moments.
Effects Persist: Although the experience itself is temporary, its effects are often profound and lasting: deep transformation of behavior and relationships, lasting sense of peace, joy, and meaning, changed worldview and values. The person remembers it vividly for the rest of their life.
Definition: The mystic feels unable to control the experience—it happens to them rather than being something they actively produce. James writes: "When the characteristic sort of consciousness once has set in, the mystic feels as if his own will were in abeyance, and indeed sometimes as if he were grasped and held by a superior power."
What does this mean? The person doesn't feel they are "doing" the experience. They feel "taken over" by something greater than themselves. Their normal sense of agency and control is suspended. They feel like a passive recipient of grace or divine action.
Less Essential: James considered ineffability and noetic quality essential to mystical experience—if an experience has these two qualities, it can be called mystical. Transiency and passivity are common but not absolutely necessary.
Beyond the four main marks, James and other scholars note additional features:
Philosopher Walter Terence Stace (1886-1967) built on James' work and distinguished two types:
"Looking outward" — perceiving unity within the external world. The plurality of objects in the world are transfigured into a single living entity. Everything external is perceived as unified, interconnected, and alive. Often occurs in nature—feeling that trees, sky, animals are all part of one divine reality.
"Looking inward" — perceiving unity devoid of any external objects. A loss of identity as a separate individual—one merges into the divine reality. Experience of pure consciousness with no sensory content. Described as "an experience of no-thing-ness" or "the Void". Nonspatial and nontemporal—outside space and time. The Unitary Consciousness—awareness of the self as identical with the One.
Stace considered introvertive mysticism the higher, purer form, with extrovertive mysticism being an "incomplete version" that finds its completion in introvertive experience.
James made an important cumulative case based on mystical experiences:
This is called James' "pluralism argument"—the universality of mystical experience across diverse traditions suggests they're accessing something genuinely real.
James addresses a crucial question: Do mystical experiences provide evidence for God or ultimate reality?
For the experiencer: Mystical experiences are absolutely authoritative. Why? Because they seem to be direct perceptions of reality, just like sense perceptions. If we trust our senses to give us knowledge of the physical world, we should trust mystical experiences to give knowledge of spiritual reality—at least for the person who had the experience.
For outsiders: Mystical experiences are NOT authoritative. People who didn't have the experience have no obligation to accept the mystic's claims. Just as someone who has never seen red has no reason to believe your description of it, someone who has never had a mystical experience has no reason to accept the mystic's interpretation.
James' Conclusion: Mystical experiences "break down the authority of non-mystical consciousness"—they show that ordinary rational consciousness is "only one kind of consciousness". They open up the possibility of other orders of truth and other ways of knowing reality. But they don't prove anything to those who haven't experienced them.
"Mystical states seem to those who experience them to be also states of knowledge. They are states of insight into depths of truth unplumbed by the discursive intellect. They are illuminations, revelations, full of significance and importance, all inarticulate though they remain; and as a rule they carry with them a curious sense of authority for after-time."
"The handiest of the marks by which I classify a state of mind as mystical is negative. The subject of it immediately says that it defies expression, that no adequate report of its contents can be given in words. It follows from this that its quality must be directly experienced; it cannot be imparted or transferred to others."
