In this episode special guest Leigh Brasington, Buddhist meditation teacher and author of ‘Right Concentration, A Practical Guide to the Jhanas’, joins the ongoing conversation featuring: - Shinzen Young, meditation teacher and neuroscience research consultant - Chelsey Fasano, a Columbia University neuroscience student, - Dr Jay Sanguinetti, Assistant Director for the Center for Consciousness Studies and Research Professor at the University of New Mexico In this episode Leigh shares his work with jhana meditation and neuroscience, summarising his 2013 paper ‘Case Study of Ecstatic Meditation’ and showing his brain scans in profound states of samadhi.
