Illusions' has certainly one of the requirements for a best-seller in the field of pop mysticism: that easiness which is both its charm and its danger.

Richard David Bach (b. June 23, 1936, Oak Park, Illinois) is an American writer. He is widely known as the author of the hugely popular 1970s best-sellers Jonathan Livingston Seagull, Illusions: The Adventures Of A Reluctant Messiah, and others. His books espouse his philosophy that our apparent physical limits and mortality are merely appearance. He claims to be a direct descendant of Johann Sebastian Bach. He is noted for his love of flying and for his books related to air flight and flying in a metaphorical context. He has pursued flying as a hobby since the age of 17.
