The Voice of Knowledge is the fourth book in the Toltec Wisdom series by the best-selling author of The Four Agreements. Don Miguel Ruiz explores the concept of "impeccability of the word" as a simple yet potent prescription for countering the judgmental inner "voice of knowledge." Adhering to "the word" - saying only what you mean, refusing to speak against you - allows anyone to transform those inner tyrannical thoughts into a voice of self-trust and integrity. Knowledge then becomes an ally, and life becomes an expression of the authentic self.
