Biblical Entheogens: a Speculative Hypothesis

Time and Mind January 1, 2008 Benny Shanon 43 citations

A speculative hypothesis proposes that ancient Israelite religion involved the use of entheogens, specifically plants containing psychoactive molecules similar to those in the Amazonian brew ayahuasca. The hypothesis reexamines Old Testament texts about Moses, noting that two plants native to the Sinai peninsula and Southern Israel—a species of Acacia tree and the bush Peganum harmala—contain the same psychoactive compounds found in ayahuasca's ingredients. The argument draws on comparative experiential-phenomenological observations, linguistic analysis, exegesis of ancient Jewish texts and other Mideastern traditions, anthropological lore, and ethnobotanical data to support the idea that these plants were used sacramentally.

The Light from the Forest: The Ritual Use of Ayahuasca in Brazil

Time and Mind January 1, 2011 David Luke 6 citations

The article examines the ritual use of ayahuasca in Brazil, tracing its historical and cultural significance within indigenous and syncretic religious contexts. It describes how ayahuasca, a psychoactive brew, is employed in ceremonies to facilitate spiritual insight, healing, and community bonding. The text highlights the continuity of these practices from pre-colonial times to contemporary urban settings, noting their adaptation and legal recognition in Brazil. It argues that ayahuasca rituals represent a form of embodied knowledge and cultural heritage, challenging Western dichotomies between nature and culture, and between the sacred and the secular.

The psychedelic explorer’s guide: safe, therapeutic, and sacred journeys

Time and Mind October 2, 2014 3 citations

A critical book review of James Fadiman's The Psychedelic Explorer's Guide finds the work frustrating and unlikely to persuade skeptics. The book is clearly structured but opens with controversial material without preparatory data. Fadiman acts more as editor than author, compiling extracts that are disparate in tone and lacking overall synthesis. His informal, personal writing style undermines scientific credibility. The book's ethical stance is mixed: it responsibly advises against illegal activity and includes safety warnings, but assumes readers have personal psychedelic experience and implies such experience is necessary to understand the research. Fadiman's spirituality is presented as fact without theological grounding.

An experimental investigation into the oxygen consumption of upper palaeolithic illumination technology: a response to Kedar, Kedar, & Barkai

Time and Mind August 11, 2025 A. Whitehead, Christopher L. Scott, Jennifer C. French 1 citation

Upper Palaeolithic parietal art deep in caves required artificial lighting. Kedar, Kedar, & Barkai proposed that oxygen consumption by lamps, combined with poor ventilation, caused hypoxia-induced altered states of consciousness that influenced ritual and art. This experimental study tested fat-burning lamps and found they extinguish at 17% oxygen, well above the hypoxia threshold. Exhaust gases—carbon monoxide and carbon dioxide—were also produced at rates too low to induce altered states. The results do not support the hypoxia hypothesis.

Potential identification of an entheogenic plant species on the Chu Silk Manuscript

Time and Mind January 2, 2021 B. Pothier 1 citation

The Chu Silk Manuscript, the earliest known Chinese illustrated manuscript from around 300 BCE, depicts plants on its four corners, long considered mythical trees. This analysis suggests that some of these plants closely resemble Caesalpinia decapetala (Yun-Shih), a hallucinogenic plant with recorded shamanic power in the first known Chinese herbal, the Pen-ts’ao Ching, compiled from oral sources near the beginning of the common era. The plant's geographic distribution, shape, and documented shamanic use support its possible depiction on the manuscript, potentially identifying substances used as trance-facilitating drugs in shamanic rituals of the Chu state era and earlier.
