"Emanuel Swedenborg" was a Swedish scientist, philosopher, theologian, revelator, and mysticism/mystic. He is best known for his book on the afterlife, Heaven and Hell (Swedenborg)/Heaven and Hell (1758).
Swedenborg had a prolific career as an inventor and scientist. In 1741, at age 53, he entered into a spiritual phase in which he began to experience dreams and visions, beginning on Easter weekend of 6 April 1744. This culminated in a 'spiritual awakening', in which he received revelation that he was appointed by the Lord to write The Heavenly Doctrine to reform Christianity. According to The Heavenly Doctrine the Lord had opened Swedenborg's spiritual eyes, so that from then on he could freely visit heaven and hell and talk with angels, demons and other spirits; and the Last Judgment had already occurred, in 1757. However, he tells us that at this day it is very dangerous to talk with spirits, unless a person is in true faith, and is led by the Lord.If you enjoy these quotes, be sure to check out other famous scientists!
