Beyond what happened, these qualities describe the inner texture of the experience, how it felt, what it conveyed, and what made it different from ordinary perception.
In his 1902 lectures The Varieties of Religious Experience, philosopher William James proposed that mystical states have four defining marks: noetic quality, ineffability, transience, and passivity. He considered these the hallmarks that distinguish genuine mystical experience from mere emotion or imagination. We assessed all nine qualities he identified, including emotion-valence qualities like joy, peace, and love, across every account in the archive.

Each quality below could apply to any type of religious experience, a vision and a moment of nature mysticism can both be ineffable, both noetic. The qualities describe the phenomenology, not the content. Percentages show how often each appeared across the 2,080 accounts.
The experience conveyed genuine insight, meaning, or knowledge, not merely emotion, but a felt certainty about the nature of things. People describe knowing things they could not previously have articulated, or having longstanding uncertainties resolved in an instant. James considered this the defining hallmark of genuine religious experience: it gives its possessor a sense of revelation.
An overwhelming sense of joy, happiness, or bliss that exceeded anything previously experienced. Consistently described as categorically different from ordinary happiness, not a more intense version of the same thing but something of an entirely different order. It often arrives alongside other qualities and is one of the most reliably reported features across all traditions.
A deep calm that transcended circumstances, often described as entering a state of peace rather than simply feeling peaceful. Distinguishable from the absence of anxiety: it is described as a positive quality, as present and real as anything else in the experience. It often persists after the experience ends, at least for a time.
The experience could not be adequately conveyed in words, language felt inadequate, approximate, or even distorting. This is a recurring observation across all traditions and all time periods. Even highly educated and articulate writers acknowledge that their descriptions fall short. The recognition of ineffability is itself one of the most consistent features of the phenomenon.
A felt sense of being in the presence of something holy, set apart, or ultimately real, distinct from the ordinary world and carrying a weight or significance that ordinary things do not. Rudolf Otto described this as the numinous: an awareness of the mysterium tremendum, the holy other. It may or may not be framed in explicitly religious terms.
A mixture of fear and reverence, the classic "numinous" quality described by Otto as the experience of something vastly greater than oneself. Not terror, but awe at something immeasurably greater: the appropriate response to an encounter with ultimate reality. This quality distinguishes many religious experiences from merely pleasant or comfortable spiritual states.
The experience conveyed or consisted of love, either the sense of being loved unconditionally and completely, or a spontaneous love that the person felt for all things. Often described as a love that was both personal and cosmic: felt as directed specifically at them, while simultaneously universal. Many accounts describe this quality as the central content of the experience.
The experience happened to the person rather than being produced by them, they describe themselves as receivers, not agents. Even when preceded by prayer or other preparation, the experience arrives as something given rather than achieved. People often emphasize their own lack of seeking or readiness: the experience came despite, not because of, what they were doing.
Time seemed to stop, expand, or become irrelevant. The experience existed outside ordinary temporal sequence, what seemed like moments might have lasted hours, or an extended experience might have corresponded to only seconds. This quality often correlates with the depth and intensity of the experience: the most transformative accounts frequently include some disruption of ordinary time perception.
