Emanuel Swedenborg was a Swedish scientist, philosopher, theologian, revelator, mystic and founder of Sweden borgianism. He is best known for his book on the afterlife, Heaven and Hell (1758).
Swedenborg had a prolific career as an inventor and scientist. In 1741, at 53, he entered into a spiritual phase in which he began to experience dreams and visions, beginning on Easter Weekend, on 6 April 1744. It culminated in a ‘spiritual awakening’ in which he received a revelation that he was appointed by the Lord Jesus Christ to write The Heavenly Doctrine to reform Christianity.
