Wasson and María Sabina's mushroom ceremony

R. Gordon Wasson and María Sabina’s mushroom ceremony in Huautla de Jiménez brought a Western seeker into a practice that had long been guarded from outsiders, but it did not mean the same thing to both participants. Wasson approached the encounter with a theory about mushrooms and the origins of religious experience; María Sabina belonged to a living Mazatec tradition in which mushrooms were used for healing and divination. The ceremony became a landmark in Wasson’s account of visionary experience, and a turning point in the public exposure of mushroom use, while also revealing how an outsider’s interpretation could recast an indigenous practice in terms familiar to him.

The Search and the Secrecy

Wasson’s journey had begun before he met María Sabina. He and his wife had initially looked toward Asia for the divine mushroom, until Richard Evans Schultes redirected their attention to the Americas. Reports from missionaries and anthropologists suggested that mushroom practices might survive in the remote mountain villages of southern Mexico. In 1953, Wasson made the first of ten trips to Mexico and Central America. Several took him to Huautla de Jiménez, in Oaxaca, after a missionary informant told him that healers there used mushrooms.

Access was difficult. Some locals denied knowing about the mushrooms; others said the practice had ended or survived only in another village. The reticence had a history: after the Spanish conquest, sacramental mushroom use had been driven underground, and the practice had remained secret from Westerners for centuries. Accounts of earlier use, including the sixteenth-century description by the Spanish missionary Bernardino de Sahagún, presented mushrooms within religious observances that could involve visions and communal reflection. That historical record, however, did not establish that the practice Wasson encountered in the 1950s had the same purpose or meaning.

Colonial suppression shaped the encounter even though it belonged to an earlier era. Spanish authorities treated mushroom ceremonies as a challenge to the church’s religious authority. Missionaries condemned the practice, mushroom stones were broken, and Indigenous people faced interrogation over religious uses of mushrooms and other plants. In 1620, the Roman Catholic Church formally condemned the use of plants for divination. Against this background, the reluctance Wasson met was not simply an obstacle in his research: it reflected a tradition that had endured under pressure and had reason to be wary of outsiders.

The Ceremony and Wasson’s Interpretation

Wasson gained access by telling María Sabina that he was worried about his son in New York and wanted to know about his son’s whereabouts and well-being. The request fit the contemporary use of mushrooms for divination. On returning to New York, Wasson believed he found that what he had learned during the ceremony was accurate on both counts. The episode strengthened his conviction that the experience had disclosed knowledge, but it also showed that he entered the ceremony under a stated purpose different from the large historical question he hoped the experience would answer.

Wasson had already developed a theory that psychoactive fungi might have played a profound role in humanity’s religious past. After the ceremony, he interpreted his experience as support for the idea that mushrooms could open access to worlds beyond ordinary human horizons and might even have helped give early people the idea of God. For him, the encounter made the language of ecstasy personally meaningful: visionary experience was no longer merely something reported by someone else. His account linked the ceremony to a broad speculation about the origins of religion, not just to the immediate question he had brought to María Sabina.

The book places that interpretation alongside a distinction Wasson knew but did not allow to govern his public framing. By 1955, many Mazatecs had become devout Catholics, and mushrooms were being used not simply for worship but to heal the sick and to divine the whereabouts of missing people or important possessions. María Sabina later told an interviewer that people had not traditionally taken the mushrooms solely to find God; they took them to help the sick recover. Thus Wasson’s experience could be personally profound without serving as proof that the ceremony’s contemporary purpose was the one he assigned to it.

An Encounter Recast for a Wider Audience

Wasson presented María Sabina as a religious figure and the ceremony as a form of communion. The book argues that this framing folded together distinct things: the historical possibility that mushrooms had once served as a sacrament, the uses they had in Mazatec communities in the 1950s, and Wasson’s own theory about religion. His interpretation gave the ceremony a legible place in a Western debate about divine experience, but it also displaced the practical healing and divinatory purposes through which María Sabina understood the work.

The contrast was not merely a disagreement about terminology. A sacramental interpretation made the ceremony resemble a direct route to the divine, while the account of healing and divination situated it within the needs of people seeking help. The book notes that Wasson knew of those contemporary uses, which makes the gap between his understanding and María Sabina’s more consequential: his public story did not arise only from a lack of information. The ceremony therefore stands both as an encounter across religious frameworks and as an example of how an observer’s prior theory can shape what an experience is made to signify.

Publicity and Consequences

The ceremony’s importance expanded dramatically when Wasson published his account. His article in Life reached millions of readers; his appearance on the CBS program Person to Person carried the story to tens of millions more. Other magazines followed with first-person accounts of mushroom experiences, using mushrooms Wasson had brought back. He also conducted ceremonies in his Manhattan apartment, and an exhibition on magic mushrooms followed at the American Museum of Natural History in New York. A practice that had been concealed from Westerners for generations entered mass media as a newly discovered source of extraordinary experience.

That exposure was not a neutral transmission of knowledge. Wasson’s account made the ceremony visible by turning it into a story about the search for God, while María Sabina’s healing context was less prominent in the version that traveled widely. The book also notes that Wasson did not consistently protect her identity: in the same week his Life article appeared, he self-published a book retelling her story without disguising her name. On a later return trip, a man who introduced himself to Wasson as a pharmaceutical-company chemist was in fact an agent for the Central Intelligence Agency, seeking mushrooms for the agency’s research program. These later developments show how quickly an encounter grounded in a local healing practice became entangled with publicity and outside institutional interests.

The ceremony’s lasting significance consequently lies in two accounts that cannot be collapsed into one. For Wasson, it confirmed the power of mushrooms to open visionary worlds and fed a theory about religion’s beginnings. For María Sabina, the practice belonged to a tradition of care and divination, not simply a quest for God. The public story amplified Wasson’s interpretation, while the book’s return to her distinction makes visible what that amplification left out: a ceremony can transform an observer’s understanding and still be misrepresented by the account that makes it famous.
