Sam Harris shares an audio essay exploring how psychedelics are, for many, the only way to glimpse "the vast firmament beyond the prison walls" of the "conceptual mind"—and often serve as the gateway to meditation. He also discusses how the very profundity of the psychedelic experience can distract us from the true purpose of mindfulness—the recognition that consciousness is always already free, in every moment. Also included are highlights from the Waking Up app created for a recent Tim Ferriss podcast.
