Long before researchers measured what trees do to cortisol levels, one Scottish-American wanderer walked into the wilderness and never fully came back. He brought something extraordinary out with him.


Today’s Teacher

John Muir (1838 – 1914) Scottish-American naturalist, writer, wilderness wanderer, and founding father of the modern conservation movement


The Teaching

“The clearest way into the Universe is through a forest wilderness.” — John Muir, John of the Mountains: The Unpublished Journals of John Muir, 1938


In His Own Words

“Climb the mountains and get their good tidings. Nature’s peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you, and the storms their energy, while cares will drop off like autumn leaves.” — Our National Parks, 1901

“I only went out for a walk and finally concluded to stay out till sundown, for going out, I found, was really going in.” — John of the Mountains: The Unpublished Journals of John Muir, 1938

“The clearest way into the universe is through a forest wilderness. Most people are on the world, not in it — have no conscious sympathy or relationship to anything about them — undiffused, separate, and rigidly alone like marbles of polished stone.” — John of the Mountains, 1938

“In every walk with nature, one receives far more than he seeks.” — Steep Trails, 1918


Who He Was

He arrived in America from Dunbar, Scotland at the age of eleven, dragged by a strict Calvinist father into the Wisconsin frontier, where he learned to work the land before he learned to love it. His father drove the children hard — rising before dawn, working until dark, memorizing scripture by lamplight. It was a childhood shaped by severity. And yet something in the boy kept drifting toward the trees at the edge of the fields, the hawks over the meadow, the particular quality of light just before rain.

He studied at the University of Wisconsin, where a professor introduced him to botany and changed everything. He walked — literally walked — a thousand miles from Indiana to the Gulf of Mexico, journal in hand, cataloguing every plant he encountered. He arrived in Yosemite Valley in 1868 and felt, by his own account, as though he had come home to a place he had never been. He built a small cabin beside a stream, slept under open sky, and began writing the letters, articles, and books that would eventually convince a nation that some land was worth keeping wild.

He co-founded the Sierra Club in 1892. He walked Theodore Roosevelt into the wilderness for three days in 1903 and walked him back out having secured the framework for what would become the national parks system. He was not a man who worked from behind a desk. He was a man who believed that going out far enough, long enough, quietly enough, you would eventually encounter something in the natural world that had the power to set the anxious mind completely free.


Why This Teaching Matters Today

Nature-based healing has moved from the margins to the center of the 2026 wellness conversation. Researchers now document what Muir intuited from a lifetime of wandering: that time in natural settings measurably reduces cortisol, lowers blood pressure, improves sleep, and restores the kind of soft, undirected attention that screens systematically deplete. The Japanese practice of shinrin-yoku — forest bathing — has accumulated a substantial scientific literature. Prescription nature programs now operate in the United Kingdom and Scandinavia.

But Muir’s contribution runs deeper than the evidence for any single wellness trend. He was describing a shift in identity: the difference between being someone who moves through the world managing their tasks and metrics, and someone who occasionally remembers they are a creature, animal and breathing, living inside a larger living world. That shift does not require a national park or a week off. It requires only a willingness to step outside, slow down, and look at something that is not a screen with genuine, unhurried curiosity. Muir did that every day of his life and considered it the most important work he ever did.


Your Morning Practice

Step outside this morning before you open any device — even for five minutes. Stand on the ground, look up at the sky, and find one natural thing to observe with real attention: a cloud formation, a bird on a wire, the way light moves through a tree, the temperature of the air against your arms. Do not photograph it. Do not describe it to anyone. Simply look at it until you feel it actually arrive in you.

Muir believed this was not a luxury reserved for wilderness adventurers. He believed it was the daily minimum required to remain a fully alive human being. Five minutes outside, attending honestly to the living world, is a different kind of morning than five minutes scrolling — and the difference accumulates.


“Going out, you will find, is really going in.”

Frequently Asked Questions

What is John Muir’s most important teaching? At the heart of everything Muir wrote is one conviction: that time spent in genuine contact with the natural world is not recreation — it is restoration. He believed that the human mind and spirit are nourished by nature in ways that no built environment can replicate, and that making space for wilderness, even in small daily doses, is one of the most essential things a person can do for their own well-being and clarity of purpose.

What is nature-based healing and does it actually work? Nature-based healing refers to the restorative effects of time spent in natural environments — from forest walks to gardening to simply sitting near a body of water. Research consistently shows that even short periods in natural settings reduce stress hormones, lower heart rate, and improve mood and cognitive function. What Muir described as the “good tidings” of the mountains, scientists now measure in blood panels and brain scans.

How do I start a daily nature practice if I live in a city? You do not need wilderness. A single tree in a courtyard, a patch of sky above a street, a pot of soil on a windowsill — any natural element, attended to with genuine curiosity rather than glanced at while walking somewhere else, begins to deliver the benefit. The key is unhurried, undirected attention: the same quality Muir brought to his first morning in Yosemite and his last. Start with five minutes outside before your first screen of the day.
