Pekka Ervast (b. 1875, d. 1934) was a pioneer of the Finnish Theosophical movement and the founder of the Finnish Rosy Cross. For over thirty years, he gave public lectures based on his spiritual experiences and wrote books on Rosicrucian Theosophy. Ervast left behind a large body of work, much of it compiled from his lecture series. His main themes included the ethics of the Sermon on the Mount, esoteric Christianity, and the human being as an evolving spiritual and eternal being in the school of karma and reincarnation.

This book is compiled from the works of Ervast and coherently presents his essential teachings.
