What is Hell?

Some preachers threaten hellfire, whilst others quench the flames with divine love. In this Sheldrake-Vernon Dialogue, following a suggestion of a regular listener, Rupert Sheldrake and Mark Vernon ask what sense can, today, be made of hell. Is it primarily a psychological state, in which people are locked up by distress? Is it a region of reality that some people, many people, or perhaps all people are at risk of traveling too? Does experience now shape the experience of the hereafter? How does the hell of the Greek and Judeo-Christian traditions relate to the hell realms charted in Eastern philosophies? And what does it have to do with purgatory, and with paradise?
