Ep. 174 - Andrew Michaels - Ayahuasca and Religious Freedom
Hey everybody! Episode 174 of the show is out. In this episode, I spoke with Andrew Michaels. I got to know Andrew when he came and worked with us. He’s an interesting guy with an interesting story. He is a lawyer by trade and recently released and will publish a paper entitled Ayahuasca and Religious Freedom. This is an important and prescient topic as ayahuasca is being brought to and worked with in the United States. Currently it is illegal and classified as a Schedule 1 drug. However there is now case law and precedent of groups attaining religious exemption under the Religious Freedom Restoration Act. We spoke about this process, the case history, why it important, some of the potential drawbacks, and his outlook moving forward. It was a really interesting conversation and I hope you all enjoy it.

Ep. 173 - Rael Inshan - The Sacred Mushroom: Amanita Muscaria
Hey everybody! Episode 173 of the show is out. In this episode, I spoke with Rael Inshan. Rael is an interesting guy who specializes in the amanita muscaria mushroom. I was really happy to have him on to speak about this sacred medicine as its not a topic I have covered much. We spoke about his difficult childhood and how that led him to South America to work with different indigenous medicine traditions. This eventually led him to discover the amanita muscaria mushroom in the woods near him and to begin working with it and to learn, firsthand, it’s benefits. He speaks about the wisdom it has taught him about it’s medicine on the individual level as well as the collective and a vision of a new earth that he feels the mushroom is guiding us towards.

Ep. 171 - Dr. Stephen Hussey MS, DC - The Physical and Spiritual Role of the Heart
Hey everybody! Episode 171 of the show is out. In this episode, I spoke with Dr. Stephen Hussey. Stephen has a fascinating story of having survived a widow-maker heart attack in his 30s’ He went on to deeply research the role of the heart and how to optimize its health. It led him on journey to question many of the fundamental assumption of what the heart its, it’s role in the human organism, and how to keep it healthy. We speak about some of these fundamental assumptions, the role of structured water, infrared light, and the deeper meaning behind a purely physical model of the heart.

Ep. 169 - Adrian Freedman - Music, Plant Medicines, Buddhism, & Shakuhachi
Hey everybody! In this episode, I spoke with Adrian Freedman. Adrian recently came into my radar as he was performing in a festival that I knew about. We delayed our talk unit we could meet in person and I’m glad we did. Adrian has a really deep presence and we spoke about his journey being trained in classical music, his learning the Japanese shakuhachi flute and buddhism, his encounter with Santo Daime and ayahuasca, and what he has learned in many decades walking this path. We went over three hours and I really enjoyed speaking with Adrian and trust you all will get a lot out of the depth, wisdom, and clarity of Adrian.
