Brainwaves &
Brotherhood
Four days, on a mountain above the Pacific. A small circle of men. EEG-guided neuro-optimization, the biology & spirituality of polarity and masculine-feminine integration. Plus, mental models based on cutting-edge neuroscience that will change the trajectory of your life.
Arrive Nov 25
(closing ceremony at noon on the 29th; depart the 30th)
This is a call for your full potential.
If you hear this call - Answer it!!!
Four days of in-depth spirituality, science, and brotherhood.
What is actually essential for MEN? Not just "inner child shadow work". An actual grounded, evidence based and pragmatic approach to the areas we need to build to actualize our potential. A 4 day intensive geared towards multiple dimensions of growth. A critical one of these is developing deeper FOCUS, arguably the key differentiating ability for success in this age of distraction....
How? Well... one of the ways is Dr. Manesh Girn PhD, (a published neuroscientist) will be using research-grade EEG's so each man can see, in his own brain, what these four days actually do to his nervous system. This means we're not guessing, we're not projecting... we're actually MEASURING the leaks, and measuring the shifts (or lack thereof) over the days.
Most men are either
too rigid or too soft.
As men we typically fall in to one of two categories... We either armor up and call it strength, or collapse into the "weak nice guy" and call it integrity. Either way, we lose the potency of what makes a man magnetic, grounded, and embodied toward a life of service and purpose.
Four pillars. One integrated week.
Neuroscience & EEG
Dr. Girn brings research-grade EEG to the experience. We measure baseline states, then track how breathwork, meditation, ceremony, sauna, cold, and group practices actually shift your brain. You leave with your own personalized data, and a clear map of what tunes your nervous system. No more guessing, assuming or projecting. You will KNOW.
Polarity & Women's Cycles
The biology of POLARITY: magnetism, attraction and our differences. Hormones, neurotransmitters, and the four phases of a woman's cycle... what is actually happening in her body and how to relate to it without guessing. Plus: men have cycles too. We'll break down all the "tips & tricks" to optimize.
Neural & Hormonal Optimization
Practical, evidence-based protocols for testosterone, dopamine, cortisol, sleep, and stress resilience. How to train your nervous system the way an athlete trains a body and how to keep it after you go home. Habit reformation and weekly calls on the Integrated Masculine Platform after the retreat to keep your a** in check!
Mental Models for a Better Life
The frameworks Matthew & Manesh have spent a decade collecting... Mental models and frameworks for masculinity and leadership, Hermetic philosophies, cutting-edge neuroscience, Eastern & Christian mysticism, Jungian shadow, sales/marketing, and modern psychology.

See your nervous system
change in real time.
Almost all men's work asks you to take its claims on faith and research and testimonies. We don't. Dr. Girn (published in Nature Medicine, PNAS, and Brain) brings clinical-grade EEG so we can actually record what happens to your brain during breathwork, deep practice, sauna-cold cycling, and group works, etc etc etc .
- Individual baseline reading on Day 1
- Live sessions during practice and integration
- Personalized debrief on what tunes (and detunes) your brain
- General & Customized take-home protocol calibrated to your specific data
A mountain sanctuary above the inlet.
A private space perched on a ridge with eastward views to Mount Baker, the Gulf Islands, and the moon rising over the Pacific.
Pool, outdoor sauna, hot tub, fire circle, lounges under cedars, and miles of trails out the back door. Built perfectly for the kind of week we have designed.





Five nights. Four days of work.
A full daily schedule and preparation guide will be provided closer to the start date.

Matthew
Matthew has spent over a decade coaching men (and women) across sales and masculine leadership, fitness and finances, neuroscience, psychology, Hermetic philosophy, Christian mysticism, and nervous system regulation. He didn't pick a lane because the lanes are the problem... they lack nuance and throw out the good with the bad. He's always about the AND. The "AND model."
He's also spent that decade inside every flavor of men's work that exists. The redpill guys wanted him angry. The soft men wanted him endlessly processing. The business bros wanted him rich. The spiritual bypassers wanted him passive and "always content". He brings the mental models that bridge them.

Dr. Manesh Girn
Dr. Manesh Girn is a neuroscientist, biotech founder, men's work facilitator, and leading voice in psychedelic research and the neuroscience of personal transformation. His work applies cutting-edge brain science to the frontier of psycho-spiritual transformation and human flourishing.
He holds a PhD in neuroscience from McGill and completed his postdoctoral fellowship at UCSF under Robin Carhart-Harris, studying the neural mechanisms of psychedelic experiences.
He's Co-Founder and CEO of Five Discovery, a biotech company developing next-generation neurotherapeutics for neurodegenerative disease, and Scientific Director of The Center for MINDS. Cited nearly 3000 times, his research has appeared in top academic journals including Nature Medicine, PNAS, and Brain.
Dr. Girn has over a decade of experience in men's work (both as a member and as a leader). From 2018 to 2022, he started and led the first Arka Brotherhood (then Samurai Brotherhood) squad in Montreal. Since then, he's become a 200-hour trained Tantra teacher in the Kashmir Shaivism tradition, spent over a year in Jungian analysis doing deep shadow work, and is currently in leadership training with Sacred Sons.
Bringing together his diverse background, Dr. Girn bridges science and spirituality to help men attain inner harmony and mastery, and brings tools like EEG hardware that gives Integrated Masculine an edge that isn't found elsewhere.
Twelve men. By application.
This is for the man who…
- Has done some work, and is ready to go deeper than"just another Men's weekend" workshop.
- Wants the psycho-spiritual AND the "real" neuroscience/biology.
- Is honest about the gap between who he is and who he could be.
- Wants brotherhood with men who are actually building something.
This is not for the man who…
- Wants or needs to be told what to think.
- Doesn't want to be challenged and just "needs to be held/heard."
- Is unwilling to sit with discomfort: his own or another man's.
- Wants ideologies dressed up as transformation.
Claim Your Seat
Four days that pay you back for years.
Secure your spot at early-bird pricing, or book a quick discovery call with Matthew to see if it is a good fit. However, if you've read this page, and you believe it to be, then it most certainly is.
A 30-minute call. Not a hard-pitch... just a conversation about whether this is the right fit for you.
