You’re most likely familiar with Dr. Dan Siegel and his pioneering work to understand the mind and help us live more joyfully. You probably aren’t familiar with his childhood story in which his joy and innocence set in motion the death of something he dearly loved.

When Dan arrived at the Hoffman Process retreat site and stepped out of his car, he was immediately greeted by one of the rabbits who lives on the over 180 acres there. When he saw this rabbit, an array of feelings and sensations swept through his body. A few days later, as Dan’s Process was well underway, a fawn and its mother would open the door wider into the deep work of Dan’s Process.

The Hoffman Process offers a science-based, courageous week of transformation. It’s a week of experiential learning incorporating everything, including the land and everything alive. It opens the door to what Dan calls “the plane of possibility,” also referred to as Love by Dan. With one foot in the practical science and the other in the world that opens us to the spiritual aspects of our nature, we step into the possibility and opportunity to heal what has often followed us nearly our entire lives.

In this nearly-an-hour conversation, Dan shares his journey of studying the mind and the results and insights of his decades of research and practice with his clients. Drew, our host, and Hoffman teacher Marc Kaplan join in for this amazing conversation. Marc was Dan’s teacher at the Process and together they share insights into much of what transpired for Dan. Dan’s deeply delightful and joyful qualities thread their way through this conversation. What a gift.
