Secret Doctrine of the Rosicrucians

This is one of the numerous Yogi Publication Society (YPS) books which have been attributed to William Walker Atkinson under pseudonym. It bears strong similarities to The Kybalion, which is also known to have been authored by Atkinson. The material was later re-worked as one of the volumes in his series The Arcane Teachings. The term Rosicrucian (symbol: the Rose Cross) describes a secret society of mystics, allegedly formed in late mediaeval Germany, holding a doctrine "built on esoteric truths of the ancient past", which, "concealed from the average man, provide insight into nature, the physical universe and the spiritual realm." In later centuries many masonic and occult societies have claimed to derive their doctrines, in whole or in part, from the original Rosicrucians.
