William "Brother Bear" Koroskenyi:
A Journey of Awakening Through Plant Medicine
From an early age, William "Brother Bear" Koroskenyi felt the hum of something deeper beneath the surface of everyday reality. As a child, he had visions of a mysterious figure—an older, wiser presence that seemed to guide and comfort him in moments of uncertainty. It wasn’t until much later, during a near-death experience in a Lakota sweat lodge on December 12, 2012, that he came face to face with this presence and realized his spirit guide had been his future self all along. This moment of revelation cracked open something deep within him, affirming that his journey on Earth was not random, but intricately woven with purpose, spirit, and destiny.
The Call of the Medicine & the Path of Apprenticeship
Though Brother Bear had first encountered sacred plant medicines in his early twenties, it wasn’t until 2013 that Ayahuasca fully called him in. That year, while attending an Ayahuasca ceremony in Iquitos, Peru, he met his future wife, Pamela—a meeting orchestrated by the medicine itself. In a vision, Ayahuasca showed him that they already loved each other, and that she would one day be the mother of his child. In that same vision, he saw the soul of his future son—an energy that had been following him for years—now unmistakably revealed to him.
Two months later, he left behind his entire life in Pittsburgh, PA, gave away all of his belongings, and moved to the Peruvian Amazon with little money and no clear plan—only an undeniable calling to surrender fully to the medicine path. What followed was a profound journey of discipline, sacrifice, and learning.
Under the guidance of Mestizo Banco-level Curandera Adela Navas, Brother Bear entered into a rigorous apprenticeship, undergoing extended periods of isolation in the jungle, deep in communion with the master plants. He undertook numerous plant dietas—each one peeling back layers of illusion and revealing new dimensions of the unseen world. In 2018, after years of disciplined training and transformation, Adela Navas coronated him as a Maestro Curandero, formally recognizing his ability to heal, guide, and safely hold ceremonies for others.
Since that time, Brother Bear has guided over 1,000 people from around the world on their plant medicine journeys, leading Ayahuasca and Huachuma ceremonies, master plant dietas, and deep healing immersions.
The Role of Sound, Icaros & Spiritual Transmission
A lifelong musician, Brother Bear always understood that sound was a gateway to the unseen realms. Long before he had the words for it, he was practicing what would later be recognized as shamanic drumming—using rhythm to induce trance states, clear energetic blockages, and connect with the spirit world.
During his dieta years, the plants began to transmit their songs directly to him. These were not melodies he composed, but sacred icaros—healing songs gifted from the plant spirits themselves. The medicine whispered its teachings to him through vibration, and he learned to channel these frequencies through song, becoming a vessel for the pure energetic force of the elements, the plants, and the divine.
Beyond the Plants: Awakening to the God Frequency
Through his years of devotion, Brother Bear experienced a profound realization—his connection to plant medicine was never the end goal. The plants were not the destination, but rather portals to something far greater—what he calls the God Frequency. This sacred resonance is present in all life, all elements, and all beings—a cosmic current that is always available when one learns to truly listen.
For Brother Bear, the medicine path is about aligning with this frequency—learning to step out of the mind’s limitations and into the vast, interconnected intelligence of the universe. The deeper he went, the more he understood that healing is not about fixing something broken, but about remembering one’s true, limitless nature.
Building a New Life in the Amazon & the Birth of the Avatar Centre
In 2014, as Brother Bear and Pamela prepared to welcome their son into the world, he had another vision—this time of a powerful Grizzly Bear, standing beside him, embodying the spirit of his unborn son. He knew then that his connection to his child was ancient, stretching beyond this lifetime. In another time, in another incarnation, he had been his son’s shamanic teacher, and now, the cycle was continuing in a new way.
That same year, Brother Bear and Pamela founded the Avatar Centre, a sanctuary for healing, plant medicine work, and spiritual awakening. Over the years, they cultivated not just a retreat space, but a living, breathing ecosystem of medicine gardens, sacred spaces, and deep community.
In 2023, he expanded his mission by founding Avatar Apothecary, bringing the wisdom of the plants to a global audience through ethically sourced Amazonian botanical tinctures and remedies.
Walking the Path with Integrity & Service
Through every step of his journey, Brother Bear has remained dedicated to the sacred, ethical, and deeply reverent path of plant medicine. He is not just a facilitator of ceremonies—he is a caretaker of the medicine, a guardian of tradition, and a bridge between the ancient and the modern world.
His work is rooted in service—helping others shed the layers that keep them from their truest selves, guiding them back into alignment with their purpose, and reminding them that the answers have always been within.
His life is proof that when one surrenders fully to the call of spirit, the universe conspires in extraordinary ways. The journey is never easy, but for those who walk the path with courage, humility, and love, the rewards are infinite.
