20th-century mystics

Eric Gutkind (also Erich; 9 February 1877 – 26 August 1965) was a German Jewish philosopher.

Bonnie Lu Nettles (née Trousdale; August 29, 1927 – June 19, 1985), later known as Ti, was co-founder and co-leader with Marshall Applewhite of the Heaven's Gate new religious movement. Nettles died of melanoma metastatic to the liver in 1985 in Dallas, Texas, twelve years before the group's mass suicide in March 1997.

Martinus Thomsen, referred to as Martinus, (11 August 1890 – 8 March 1981) was a Danish author, philosopher and mystic. Born into a poor family and with a limited education, Martinus claimed to have had a profound spiritual experience in March 1921. This experience, which he called "cosmic consciousness", would be the inspiration for the books he wrote later on which are collectively entitled The Third Testament. Some of his works have been translated into twenty languages, and while he is not well known internationally, his work remains popular in Denmark and to a lesser extent other parts of Scandinavia.
