Don Miguel tells readers that they are born in truth but grow up believing in lies — mainly about themselves. As a child one listens to the "voice of our integrity," which is rooted in truth. Once one learns to speak, he or she mainly hears the louder "voice of knowledge," which is rooted in lies and causes endless suffering. By following the guiding principles presented in this book, readers can reclaim their authentic self, just as it was before they learned to speak.
