A Great Question

Can mystical experience be induced?

Whether drugs, techniques or practice can produce the experiences the mystics describe, and whether it matters how they come.

Framing

The mystics of many traditions describe experiences of unity, light and timelessness that seem to come unbidden, as a gift, or only at the end of long discipline. In 1954 Aldous Huxley reported that a dose of mescaline had shown him something very like what they describe. His book opened a debate that has continued through the research on psychedelics in the 1960s and its revival in recent years.

Behind the debate lie older questions. Are mystical experiences all of one kind, so that the same state might be reached by different means? Or do they differ, so that a drug might produce one kind and not another? Does the value of an experience lie in the experience itself, or in what it does to the life of the one who has it? The traditions have long held that visions and raptures are not the goal, and that their fruits matter more than their intensity.

The perspectives below come from the debate itself and from the traditions it drew on.

Perspectives

Voices from several traditions, each in its own terms. They are set side by side to be compared, not ranked.

Comparative mysticism, Aldous Huxley
Scholarship
The brain filters a wider awareness down to what is useful for survival; mescaline, like fasting or prolonged prayer, can open the valve and let in something of that wider mind, a gratuitous grace that is not yet salvation.
Sources: The Doors of Perception; Heaven and Hell
Comparative mysticism, R. C. Zaehner
Scholarship
Mystical experiences differ in kind. A drug may bring a sense of oneness with nature, but not the loving union with God of the theistic mystics; to equate them is to mistake one experience for another.
Sources: Mysticism Sacred and Profane
Modern philosophy, William James
Scholarship
Experiments with nitrous oxide convinced James that ordinary waking consciousness is only one type among many, separated from others by a thin film; the mystical states must be judged by their fruits for life, not by their origin.
Sources: The Varieties of Religious Experience
Theravāda, Buddhaghosa
Scholarship
Concentration and insight are cultivated step by step, on a foundation of virtue; intoxicants cloud the mind and are forbidden by the precepts, and even the bliss of absorption is not liberation unless it is seen through by wisdom.
Sources: The Path of Purity
Vedānta, Ramakrishna
Scholarship
Ramakrishna’s states of samādhi came in the midst of devotion, often at a song or a word about God; he taught that God is realized through intense longing, purity and discrimination, and judged a seeker by love and renunciation, not by experiences.
Sources: The Gospel of Sri Ramakrishna
