“ The voice that says, “That’s the way I am,” is the voice of knowledge. It’s the voice of the liar living in the Tree of Knowledge in your head. The Toltec consider it a mental disease that is highly contagious because it’s transmitted from human to human through knowledge. The symptoms of the disease are fear, anger, hatred, sadness, jealousy, conflict, and separation between humans. Again, these lies are controlling the dream of our life. I think this is obvious. ”
