Der zweite Körper. Astral-& Seelenreisen in ferne Sphären der geistigen Welt (Taschenbuch)

His personal accounts are fascinating, and I'm curious what motivated him to dedicate his life to exploring consciousness beyond the physical realm.

Some passages felt so vivid and real that I wondered if they were based on actual experiences or metaphysical beliefs. Would love to hear others' impressions.

Considering recent developments in consciousness studies and remote viewing, I'm interested in how his methods hold up today or if they seem outdated.
