"Gleanings of a Mystic" is a compilation of short essays on mystic, Rosicrucian topics, from the well known Max Heindel. These were written, apparently, over a span of some time.The subject matter is highly varied- social systems, biology, and straight-up occultism are all mentioned in multiple passages, and Atlantis-heavy references of human mythology abound, along with statements on mortality, reincarnation, and many other things.
