The first of three programmes with Geoffrey Moorhouse talking to people about insights into reality glimpsed through drugs, madness, or mysticism. Are these experiences a genuine contact with God or merely delusion?

'If you took LSD and walked into a church I guarantee you'd have a religious experience. It could be hell but it would be a religious experience.'
'The basis of the chemical religious claim is that this state in which you feel that your soul has left your body is very similar to the state described by the mystics.'
Contributors include Steve Abrams, Charles Cameron, Dr Allan Cohen, Rosalind Heywood, Fr Kenneth Leech, Dr Alan Watts, Pete Townshend
