Paul Hawken: A Love Letter to the Flow of Life

Paul Hawken — April 1, 2025

The realities of human-driven climate change are only just starting to hit home for many of us. Meanwhile, activists like Paul Hawken—along with the people who have endured the devastating impacts of environmental degradation in the places they call home—continue to raise the alarm for a planet in peril. In this podcast, Tami Simon speaks with the renowned environmentalist and entrepreneur about his latest work, Carbon: The Book of Life, an awe-inspiring read that Tami dubs “a love letter to the flow of life.”

Give a listen to their conversation on: why the climate is never really in crisis (and who is); the narratives of disconnection that perpetuate a sense of separation from life; why “the only way forward is regeneration”; how humanity’s “othering” in order to get ahead just puts us all behind; the concept of flow in the natural world; the extraordinary complexity of life and the trillions of creatures communicating with each other every day; tapping into the power of curiosity and wonder; overcoming the overwhelming inertia of the existing capitalist system; why our grief is a measure of our love; embodying the timeless qualities of compassion, cooperation, and respect; the connection between the loss of Indigenous languages and species loss; apocalypse—the revelation of that which is hidden; how the discovery of fire impacted human evolution; mystical experiences in nature; leadership—listening to all the voices; and more.

Yuria Celidwen, PhD: “Flourishing Is a Gradual U...

Dr. Yuria Celidwen is at the forefront of a historic expansion in the field of contemplative science—or the study of inner practices like meditation, prayer, and mindfulness. Until recently, researchers have primarily focused on major religious traditions such as Buddhism or Christianity. Today, Dr. Celidwen is bringing the long-overdue perspective of Indigenous cultures into the discussion. In this podcast, Sounds True founder Tami Simon speaks with Dr. Celidwen about her new book, Flourishing Kin: Indigenous Wisdom for Collective Well-Being.

Tune in for this invigorating conversation exploring: Yuria’s definition of flourishing as a gradual unfolding of aesthetic arrest; cultivating an embodied sense of your interconnection with all of creation; why Indigenous perspectives are vital for solving the climate crisis; honoring spirit, the animating principle of life; a deeper understanding of health; the direct experience of “moments of truth”; sunshine as a seed of awareness; the core right of self-determination; relating to Indigeneity respectfully; the possibility of collective flourishing; and more.

Jeffrey Rutstein, PsyD: You Can Shift the State of You...

Our understanding of the human nervous system has grown exponentially in recent years, thanks to astounding discoveries from neuroscience, Polyvagal Theory, trauma research, Attachment Theory, and other emerging fields. No longer do we see the functioning of the nervous system as an unconscious process outside of our control. Today, we know that you can actually befriend and work with your nervous system to self-regulate in the face of emotionally triggering situations, release unresolved trauma from the “stuck places” inside, and reclaim a life of integration and wholeness. Sounds True’s annual training, The Healing Trauma Program, was designed expressly for these purposes. In this podcast, Tami Simon speaks with psychotherapist and lead teacher of the program Dr. Jeffrey Rutstein.

Tune in for an eye-opening conversation on: the connection between unhealed trauma and nervous system dysregulation; raising self-awareness around your personal triggers and conditioned responses; shifting from defensiveness to feelings of safety and belonging; chronic dysregulation; accurately discerning when you’re in danger; the vagus nerve, the ventral vagal response, and the “tend and befriend” zone where we can be fully present; the interplay of genetics and your upbringing in the formation of your “go-to nervous system states”; a nervous system approach to transforming self-blame and shame into self-compassion and worthiness; three pools of energy—hyperarousal, hypoarousal, and the Window of Tolerance; the empowering firsthand experience of changing your nervous system states; why there are no “bad” nervous system states; why being in a regulated state is so critical to healthy relationships; neuroception; simple, on-the-spot techniques (or “nervous system hacks”) you can use to self-regulate, from breathwork to gentle stretching and more; the shortcomings of talk therapy; co-regulation and the social engagement zone; the four key questions of the aspiring nervous system co-regulator; severe trauma and how “the state drives the story”; meditation practice, the true self, and the inner “hijacker”; and more.
