About César Arce
Each volume in The Biohacker's Guide Collection is a step into the invisible architecture of life — where energy, frequency, and vibration converge with modern science to illuminate new paths to health, harmony, and reconnection with the Earth.

Some lives are lived in straight lines. His has been a spiral — always descending deeper, always returning transformed.
At six years old, beneath a canopy of stars in the World Organization of the Scout Movement, he learned to read what most people no longer see: the language of nature written in terrain, wind, and silence. Survival. Navigation. The invisible grammar of the wilderness. What began as a boy's adventure became a lifelong discipline of attention.
That discipline carried him into the skies. As a military pilot, he mastered celestial navigation — orienting himself by the same stars that had guided him as a child — and trained in jungle, sea, and desert survival, and elite parachuting operations. Altitude stripped away the noise of modern life. What remained, always, were the same subtle patterns and unseen forces he had first sensed in those early mountain camps.
Then came the turn inward.
Over three decades, he has dedicated himself to the ancient science of radiesthesia — the art of detecting what instruments cannot measure and language cannot easily name: the subtle energies that flow through the Earth, through water, through the living architecture of our homes and bodies. He has walked the corridors of initiatic traditions, esoteric schools, and philosophical lodges, studying the alchemical methods that transform scientific inquiry into something rarer — wisdom.
The Biohacker's Guide Collection is the fruit of that long spiral. Not a collection of theories borrowed from others, but a body of lived knowledge — tested in the field, refined in solitude, and offered now to those who sense, as he always has, that the Earth is speaking.
The question has always been the same: Are you listening?
“These five volumes are not separate books — like a fist, they are one force, one pulse, one awakening. The Earth is alive, and it speaks through energy. Geobiology, Geopathies, Radiesthesia, Radionics, and Electroculture are not fringe curiosities — they are ancient sciences rediscovered, revealing the patterns once dismissed as superstition. When you read them together, you hear not just theory, but a call: to stand differently, to plant differently, to live differently. This is the symphony of the invisible — and it is waiting for your hands to play it.”

This work would never have seen the light of day without the encouragement, curiosity, and faith of those who walked beside me during its creation.
What began as a simple curiosity evolved, over the years, into a profound passion — fueled by countless conversations, shared questions, and sparks of inspiration. To all those who listened with genuine interest and urged me to keep exploring and writing, I owe a deep debt of gratitude.
Thank you for being part of this journey — because together, we are rewriting the way we connect with the Earth and ourselves.

Join us each week — discoveries, practical biohacks, and inspiring conversations about health, energy, and the invisible forces that shape our lives.
Geobiology
The Earth Heals. All you must do is see Nature's signals.
Geobiology introduces the science of how the Earth's natural geomagnetic fields, Schumann resonances, and telluric currents influence health, sleep, and emotional balance. Discover how invisible geomagnetic grids — the Hartmann and Curry networks — intersect beneath your home, creating geopathic stress zones that silently erode your vitality. Learn to detect these disturbances and harmonize your environment to reclaim the coherence your body has always known.
Geopathies
The Silent Saboteurs Beneath Your Feet.
Geopathies explores how underground water streams, geological faults, and geomagnetic anomalies silently disrupt biological rhythms. Combining forgotten European medical insights with modern biohacking tools, this volume reveals how to identify and neutralize the harmful zones that weaken immunity, disturb sleep, and erode long-term vitality — starting with the simplest and most powerful intervention: moving your bed.
Radiesthesia
The Art and Science of Sensing Earth's Hidden Energies.
Radiesthesia bridges physics and ancient wisdom, training you to use rods, pendulums, and your own nervous system as instruments to detect geomagnetic fields. Grounded in the science of magnetosensitivity — the same capacity that guides migrating birds — this volume empowers you to map safe and unsafe zones in any space, reconnect with your natural energetic awareness, and recalibrate your biological antenna against modern electrosmog.
Radiesthesia & Radionics Booklet
From Theory to Hands-On Exploration.
This practical companion condenses the teachings of the previous volumes into clear step-by-step exercises. Learn to locate Hartmann and Curry lines in your home, apply pendulum techniques for environmental assessment, and explore the foundations of Radionics — a forgotten art used to evaluate vitality in foods, environments, and living beings. The essential field manual for anyone putting the science into practice.
Electroculture
Farming with the Living Sky.
Electroculture revives a forgotten agricultural science that harnesses atmospheric electricity — the 400,000-volt potential between the Earth's surface and the ionosphere — to boost germination, enhance plant vitality, and multiply harvests without chemicals or heavy irrigation. From copper spirals and Christofleau antennas to simple DIY techniques inspired by Tesla, this volume blends physics, history, and hands-on practice, inviting you to reconnect with the hidden circuit between Earth and sky.
