The Great Work - The Constructive Principle of Nature in Individual Life
by J.E. Richardson
Richardson expresses his philosophy as follows, " Nature evolves a Man. Nature alone, however, can never evolve a Master. Man can make a Master by co-operating with and supplementing Nature so as to conform his life to her Constructive Principle and Process."
This is volume 3 of this highly evolved series on spiritual growth and health.
The authors and editors take great efforts to teach the reader, not only the why one needs to grow spiritually but how to do so, with proven techniques and practices.
