"The trick is in what one emphasizes.
We either make ourselves miserable,
or we make ourselves strong.
The amount of work is the same."
20th century mystic and Toltec warrior
Carlos Castaneda was an anthropologist from UCLA who, during the course of his research, introduced the world to both the Mexican philosophy known as Toltec as well as his teacher, the Yaqui Indian shaman Don Juan.
Castaneda chronicled his experience with Don Juan through a series of books. The first, The Teachings of Don Juan: a Yaqui Way of Knowledge, was actually his masters thesis--which introduced the world to Don Juan and quickly became a best seller and started a fascination with the world of shamanism and the Toltec warrior.
Although the veracity of some of his experiences (including the actual existence of Don Juan!) is questioned, the profile of a warrior is no less meaningful. The lessons he shares are powerful and echo many of the truths revealed in other classic philosophies discussing the art of living.
