Churton examines the complexities of Jesus’s teaching that “the Kingdom of God is within you” and Islamic ideas about paradise. He analyzes the beliefs of Eastern mystics and Maori, Australian Aboriginal, and Polynesian traditions as well as heavenly conceptions among Indigenous cultures of the Americas. He presents Renaissance-era understandings of Heaven’s connection to the body in the alchemical spiritual medicine of Paracelsus and the mysticism of Jacob Böhme and reveals that Emmanuel Swedenborg, followed by William Blake, controversially associated Heaven with sexuality. Churton then delves into the contemporary era, exploring Heaven from perspectives of spiritualism, psychedelic experience, communist materialism, and the arts, including John Lennon’s lyrical suggestion that we imagine that there is no heaven.
