Religious Experience

Across the nine religions, believers describe moments of encounter with the sacred — awe before the holy, a sense of union, sudden conversion, deep prayer, and pilgrimage. This mini-lesson maps the main types and the scholars who studied them, above all Rudolf Otto and William James.

Overview

What is a religious experience?

A religious experience is a moment in which a person feels they have encountered a reality beyond the ordinary — often called the sacred, the holy, God, Brahman or the ultimate.

  • It may be dramatic (a vision, a voice) or quiet (a deep sense of presence in prayer).
  • It is usually felt as something given, not chosen — it comes upon the person.
  • It typically leaves the person changed: comforted, humbled, or turned in a new direction.

Study note: phenomenology asks us to describe these experiences as the believer reports them, before asking whether they are "real".

Scholar · Rudolf Otto

Otto and the numinous

In The Idea of the Holy, Rudolf Otto argued that the heart of religion is a non-rational experience of the holy, which he called the numinous.

  • Mysterium tremendum — the holy as an overwhelming mystery that fills a person with awe and even dread.
  • Fascinans — yet it also attracts and fascinates, drawing the person towards it.
  • Creature-feeling — a sense of one's own smallness before something wholly other.

Example often cited: the prophet Isaiah's vision in the Temple, overwhelmed by God's holiness, captures this numinous awe.

Scholar · William James

James and the marks of mysticism

In The Varieties of Religious Experience, the psychologist William James studied mystical experiences and drew out four recurring marks:

  • Ineffability — it cannot be fully put into words.
  • Noetic quality — it feels like real knowledge, an insight into truth.
  • Transiency — it does not last long.
  • Passivity — the person feels held by a greater power, not in control.

James's approach: he judged such experiences partly by their fruits — the good changes they produce in a person's life.

Comparison · union across faiths

Mysticism across the religions

Many traditions describe a goal of profound closeness to or union with ultimate reality — described very differently:

  • Sufism (Islam)fana, the passing away of the self in God, sometimes reached through dhikr (remembrance of God).
  • Hinduism — the realisation, in Advaita thought, that atman (self) and Brahman are one; deep meditative absorption is samadhi.
  • Buddhism — meditative insight leading towards nirvana, the "blowing out" of craving.
  • Christianity — the contemplative tradition speaks of union with God in love.

Careful comparison: these are not simply the same experience — a monotheist's union with a personal God differs from a Buddhist's non-theistic insight. Note likeness and difference.

Practice · prayer & meditation

Prayer and meditation

For most believers, religious experience is nurtured through everyday practice:

  • Prayer can be petition (asking), thanksgiving, confession or silent contemplation. In Islam, salah (five daily prayers) shapes the day; Sufis add dhikr.
  • Meditation stills and focuses the mind — Buddhist samatha (calm) and vipassana (insight); Hindu dhyana.
  • Communal worship — shared prayer, chant and song can lift a whole congregation together.

Link: disciplined practice is often how a tradition prepares people for deeper experience, rather than waiting for a dramatic event.

?In Sufi (Islamic) mysticism, what is the term for the "passing away" of the self in God?
Practice · pilgrimage

Pilgrimage

A pilgrimage is a journey to a sacred place, undertaken as an act of devotion and often a search for spiritual experience:

  • Islam — the Hajj to Mecca and the Kaaba, a duty once in a lifetime for those able (one of the Five Pillars).
  • Hinduism — bathing in the sacred Ganges, especially at Varanasi; the vast Kumbh Mela gathering.
  • Christianity — journeys to Jerusalem, Rome, Lourdes or along the Camino to Santiago de Compostela.
  • Buddhism — sites of the Buddha's life, above all Bodh Gaya, place of his enlightenment.

Common threads: leaving ordinary life behind, hardship and effort, a shared community of pilgrims, and the hope of transformation.

Evaluation · interpreting experience

How should experiences be interpreted?

Scholars debate what religious experiences tell us:

  • Religious view — they are genuine encounters with a real sacred reality.
  • Psychological / naturalistic view — they can be explained by the mind, culture or the brain, without a supernatural cause.
  • James's pragmatism — judge them by their fruits: do they make people more loving, hopeful and good?

Balanced answer: the phenomenologist first describes the experience faithfully; questions of truth and cause come afterwards, and thoughtful people disagree.

Recap

The big ideas to know

Otto: the numinous — mysterium tremendum et fascinans; creature-feeling (The Idea of the Holy)

James: four marks of mysticism — ineffability, noetic quality, transiency, passivity; judge by fruits

Union across faiths: Sufi fana · Hindu atman-Brahman/samadhi · Buddhist nirvana · Christian union

Practice: prayer, meditation, communal worship, pilgrimage (Hajj, Varanasi, Camino, Bodh Gaya)

Interpretation: religious vs naturalistic explanations; describe first, then evaluate
