Dr. Luis Eduardo Luna explores the Amazon's profound biological and cultural
The only way to experience mind in plants is to silence the human apparatus that deals with concepts and just feel, observe, listen, and be open to pure presence without self-reflection.
Summary
- The Amazon was home to vast civilizations with advanced agriculture and rich anthropogenic soils, challenging the myth that the region could not sustain large, complex populations. - Sacred psychoactive plants like Ayahuasca are viewed as "plant teachers" and doctors that provide essential knowledge, healing, and direct access to cultural mythology. - Colonialism led to a massive loss of indigenous knowledge and the systematic persecution of sacred plant traditions, which were historically mislabeled as witchcraft or diabolical practices. - Indigenous epistemology is based on an animistic worldview where all of nature is intelligent, contrasting with the Western scientific separation of subject and object. - Emerging scientific research into plant intelligence and sensitivity aligns with ancient traditions that recognize the natural world as a communicative and subjective presence.

Amazonian Shamanism, Sacred Plants And The Wisdom Of Plant Teachers
At Biohacker Summit 2022 Helsinki, Dr. Luis Eduardo Luna Argued That The Amazon Was Not A Void At The Edge Of History, But A Living Archive Of Civilisation, Knowledge And Sentient Nature
On Friday, 3 June 2022, at Biohacker Summit 2022 Helsinki in Finland, Dr. Luis Eduardo Luna delivered a presentation that moved between anthropology, botany, history and cosmology with unusual force. Titled *Amazonian Shamanism, Sacred Plants & Healing*, the talk offered a challenge not only to Western assumptions about the Amazon, but to the intellectual habits through which modern societies had long imagined nature itself.
Luna, a former Senior Lecturer at the Swedish School of Economics in Helsinki and former Professor of Anthropology at the Federal University of Santa Catarina in Brazil, spoke with the authority of a scholar who had spent decades moving between academic research and direct engagement with Amazonian traditions. His central claim was both simple and destabilising: the sacred plants of the Americas were not peripheral curiosities, but key to understanding Indigenous knowledge, healing practices and the very history of the continent.
“We cannot understand the Americas without reference to the sacred plants,” Luna said. “These plants are absolutely crucial, and each indigenous tribe has their own sacred plants which are specific to them.”
The Amazon Beyond The Myth Of Emptiness
The first part of Luna’s talk dismantled one of the most durable colonial fantasies: that the Amazon had been an inhospitable wilderness, too poor in resources to support large human populations. He described the region not only as one of the richest reservoirs of biological diversity on Earth, but also as one of its great zones of cultural and linguistic complexity, home to hundreds of living languages across dozens of linguistic families.
He pointed to mounting archaeological evidence that had transformed scholarly understanding of the region. Far from being sparsely inhabited, the Amazon once supported extensive settlement networks, advanced cultivation systems and human-made black soils of extraordinary fertility. LiDAR scans had revealed ancient settlements and pyramidal structures, while major rock-art discoveries in the Colombian Amazon suggested cultural landscapes of immense age and scale.
In Luna’s telling, the Amazon emerged not as untouched wilderness but as a profoundly shaped world, one in which human beings had long participated in the making of ecologies. The old European belief that the rainforest had stood outside history had not survived the evidence.
The Great Loss Of Knowledge
Yet if the Amazon was once full of cities, gardens, technologies and ceremonial systems, Luna made clear that much of this world was shattered after conquest. He drew attention to the catastrophic demographic collapse that followed European contact across the Americas, when disease, violence and dispossession killed the overwhelming majority of Indigenous people within little more than a century.
With those deaths came an immense loss of knowledge. Libraries were burned. Ritual specialists were persecuted. Sacred practices were criminalised. Traditions involving psychoactive plants were frequently recast by colonial authorities as witchcraft or devilry.
Luna traced this repression across the hemisphere, from Mesoamerican mushroom and morning glory rites to the ritual use of peyote, cohoba and Amazonian snuffs. Again and again, he showed, plants that had served as medicine, revelation or divination were denounced as signs of moral danger. The result was not merely spiritual censorship, but epistemicide: the destruction of entire ways of knowing.
Plant Teachers, Not Intoxicants
Luna was careful with language. He rejected the flattening vocabulary often used in modern discussions of such substances. Rather than “psychedelics”, his preferred term was “sacred plants”, a phrase that restored ceremonial and relational meaning to what modern pharmacology often reduced to chemistry.
In Amazonian traditions, he said, these plants were not simply consumed. They were approached as teachers, doctors and bearers of knowledge. Ayahuasca, yaje, tobacco, brugmansia and other species belonged to systems in which learning was disciplined by diet, isolation, ritual preparation and moral seriousness.
He recalled the words he had learned in the field: plants were maestros. They taught. They healed. They disclosed worlds.
“We do not become shamans by eating game or the food from our gardens, but through the trees of the forest,” Luna said, quoting Indigenous understanding. “It is the sacred plants that reveal the spirits’ words and spread them far and wide.”
This idea, which Luna had helped articulate decades earlier through his work on “plant teachers”, stood at the centre of his presentation. The plants did not merely alter consciousness. They formed part of an epistemology, a way of coming to know reality through relation, encounter and transformation.
Ayahuasca And The Chemistry Of Relation
The lecture did not abandon science. On the contrary, Luna moved fluently between Indigenous knowledge and biochemical explanation. He discussed ayahuasca and yaje as combinations of plants whose effectiveness depended on a sophisticated synergy. Harmine-containing vines, he noted, made it possible for DMT-bearing leaves or admixtures to become orally active by inhibiting monoamine oxidase.
This was no crude mystification. It was evidence, he suggested, that Indigenous experimentation had arrived at complex botanical knowledge through long historical engagement with the forest. The plants were sacred, but they were also precise.
Luna’s own intellectual journey had been shaped by these questions. He described encounters in Colombia in the 1970s, including time spent with Terence McKenna, and later fieldwork in Peru and Brazil. Those experiences pushed him toward anthropology, chemistry and comparative religion, as he tried to understand what he had witnessed. His scholarship, like his lecture, was marked by a refusal to separate direct experience from disciplined study.
A World Alive With Mind
If the first challenge in Luna’s talk was historical, the second was philosophical. Indigenous Amazonian knowledge, he argued, rested on an animistic worldview that modern Western thought had too often dismissed. But “animism”, in his use, did not mean childish fantasy or projection. It meant recognising subjectivity, intelligence and communicative capacity in the more-than-human world.
“Animation is the recognition that there is mind in life and subjectivity in everything which exists in nature,” Luna said. “We live in an intelligent planet, surrounded by millions and millions of species.”
In that vision, nature was not mute matter waiting to be measured from outside. It was expressive, relational and participatory. Mountains, rivers, winds, animals and plants did not merely exist. They addressed, signalled, warned, taught.
“In indigenous cultures, nature speaks,” Luna said. “There is no element of the landscape that is void of expressive resonance and power. Any movement may be a gesture; any sound may be a voice, a meaningful utterance.”
Against the Cartesian split between subject and object, Luna proposed what he described as a relational epistemology. Knowledge did not come only from standing apart and observing. It also came from entering into relation, from learning how to listen, and from allowing oneself to be changed by what one encountered.
When Botany Returned To The Centre
One of the most striking features of Luna’s lecture was the extent to which he framed this Indigenous worldview not as an artifact of the past, but as something toward which modern science was beginning, cautiously, to move.
He cited emerging work on plant sensitivity, responsiveness, memory and intelligence, as well as contemporary thinkers calling for botany to be restored to a central place in the life sciences. If plants were understood on their own terms rather than merely as passive background to animal life, he suggested, then science itself might recover a richer account of autonomy, adaptation and ecological repair.
“Botany should regain its place at the center of the life sciences by thinking about the plant itself as an original form of life, as a model with respect to autonomy and the restoration of the environment,” Luna said.
The line carried more than academic significance. It implied that the old hierarchy, in which plants existed as scenery and humans as thinking subjects, had become intellectually untenable. The forest, in Luna’s rendering, was not a storehouse of raw material. It was a community of intelligences.
Art, Vision And The Ethnography Of The Invisible
Luna also returned to the work that had made him one of the most distinctive interpreters of Amazonian visual culture: his collaboration with the Peruvian artist and former vegetalista Pablo Amaringo. Through Amaringo’s paintings, Luna had found a way to document visionary worlds often dismissed as private or ineffable.
Those canvases, crowded with spirits, serpents, celestial architectures, luminous beings and impossible cities, became for Luna not decorative expressions but ethnographic evidence. They preserved a symbolic vocabulary of ayahuasca experience and gave form to a cosmology in which the visible world was only one layer of reality.
In the lecture, this material functioned as more than illustration. It reinforced his larger claim that sacred plants were not simply chemical triggers for hallucination. They were embedded in systems of meaning, discipline and revelation that linked mythology, healing and ecological perception.
The Forest As Teacher
By the end of the talk, Luna’s argument had widened into something larger than a defence of shamanic traditions. It became a critique of estrangement. Modern societies, he suggested, had trained themselves to privilege abstraction over attention, classification over relation, utility over reverence. The cost was not only ecological devastation, but a thinning of perception.
To know plants, he said, one had to do more than analyse them. One had to silence the conceptual apparatus long enough to observe, feel and listen. This was not anti-intellectualism. It was another discipline of mind.
At Biohacker Summit 2022 Helsinki, where many speakers explored the limits and optimisation of the human body, Luna offered a deeper provocation. Perhaps the question was not only how to enhance human performance, but how to recover participation in a living world that had never ceased to think, signal and speak.
His lecture did not ask the audience to romanticise the Amazon. It asked them to reconsider what counted as knowledge, and who or what could be a teacher. In that sense, the wisdom of plant teachers was not only about ayahuasca or sacred ritual. It was about whether modernity could still learn to hear the earth.
