EPISODE 141: FROM MOLECULES TO MEANING: HOW PSYCHEDELICS REWIRE THE BRAIN, AND WHY INTEGRATION IS THE REAL MEDICINE with Manesh Girn

Kristin invites neuroscientist and educator Manesh Girn, who breaks down what really happens in the brain during psychedelic experiences and why it matters more than ever in today’s rapidly evolving world. From the hidden beliefs shaping your reality to the powerful role of neuroplasticity, this conversation reveals how these substances can disrupt limiting patterns and open the door to deep healing and growth. You’ll gain clarity on the differences between compounds like psilocybin and MDMA, the science behind integration, and why true transformation happens long after the experience ends. Whether you’re curious, cautious, or already exploring, this episode offers grounded insight into how we can consciously reshape our minds—and ultimately, our lives.
