You’re Optimizing Everything Except the Thing That Runs It All | Dr. Kien Vuu & Stephen Zerfas

What if the most powerful upgrade you could make isn’t your routine, your diet, or your mindset, but your nervous system?

In this episode of the Thrive State Podcast, Dr. Kien Vuu sits down with Stephen Zerfas, co-founder of Jhourney, to explore the ancient science of jhana meditation — and how modern retreats are helping top executives, AI researchers, and high performers access peak states of consciousness without drugs, in under a week.

Steven’s journey started at an all-time low — a broken co-founder relationship, two lost jobs, and a 10-day silent meditation retreat that nearly broke him before it changed everything. What he discovered in those final hours became the foundation for a company dedicated to solving one of humanity’s oldest and most overlooked problems: nervous system mastery.

If you’ve ever felt like you’re running on autopilot, surviving instead of thriving — this conversation is for you.

In this episode, we explore:

• Why your nervous system is the most under-optimized system in your life
• What Jhanas are and why elite performers are calling them “MDMA without the drug”
• The #1 reason most people plateau in meditation (and how to fix it)
• Why time management is actually pain management
• How AI is being used to scale personalized meditation coaching to millions
• A live guided meditation experience you can follow along with
