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.
This etext was scanned from an original 1918 printing of this work.
