Gleanings of a Mystic: A Series of Essays on Practical Mysticism is a book by Danish-American Christian occultist, Max Heindel. It was first published in 1922 and contains the last writings of the author. The result of years of occult research, the book has twenty-four lessons based on Christianity and Rosicrucianism that were originally sent out to his students, and discusses subjects such as initiation, the Communion, marriage, baptism, the coming of Christ, and the meaning of Easter. The author founded The Rosicrucian Fellowship in 1911, and also published a Christian Esoteric magazine.
