 It extols the virtues of exploring one's own nature and instincts.
 Believers have been described as "atheistic Satanists" because they believe that God is not an external entity, but rather something that each person creates as a projection of his or her own personality—a benevolent and stabilizing force in his or her life.
 There have been thirty printings of "The Satanic Bible", through which it has sold over a million copies.
