In this recent episode of Insights at the Edge, Sounds True Founder and CEO Tami Simon sits down with Andrew —interdisciplinary scholar, lifelong practitioner of Tibetan Buddhism, and author of the new Sounds True book Total Eclipse of the Mind: Unleashing the Power of Darkness for Creativity, Healing, and Transformation—for a conversation on dark retreat: full immersion in sealed, lightless space, a practice yogis have used for centuries to accelerate inner transformation.
Across fifty years of meditation, psychedelic exploration, and a traditional three-year Tibetan retreat, Holecek calls this the single most transformative practice he has encountered—and in this interview, he explains why.
Join Tami and Andrew as they explore:
- What unfolds in the mind during prolonged darkness—and the neuroscience behind why it works so deeply
- How awareness descends through the conscious, subconscious, and collective unconscious—and what lies waiting at the very bottom
- Why dark retreat functions as a “sober psychedelic,” prompting the brain to produce its own endogenous DMT
- Enantiodromia—the moment when extreme contraction abruptly flips into extraordinary openness
- Meeting panic, trauma, and unwanted experience through the “reverse meditation” principle: feel it, but don’t feed it
- Why the dark dissolves all concern with appearance—and why so many people emerge in tears, feeling safe and held for the first time
- A four-step path for bringing darkness into daily life, from simple sleep masks to fully dedicated dark rooms
Recorded with both Tami and Andrew wearing blackout masks, this stands out as a most immersive listening experience.
