• Reading the Signs: The guide provides extensive lists of physical gestures to decode a person's inner emotions, even when they aren't explicitly stated.
• Interest: Signaled by maintained eye contact (over 60%), wide-opened eyes, nodding, and feet pointing toward the speaker.
• Agreement & Openness: Indicated by open palms, hands flat on the table, unbuttoned jackets, and heads inclined forward.
• Confidence & Power: Shown through firm eye contact, erect posture, a firm handshake with palms pointing downward, and "steppling" (joining fingertips together).
• Deception/Lying: Signs include avoiding eye contact, rapid blinking, constantly touching the face (mouth, ear, or nose), and projecting body parts toward an exit.

The author notes that while body language is a powerful tool, it is not absolute. Readers are cautioned not to "jump to conclusions" based on a single gesture, but rather to look for clusters of signals that align with spoken words for more accurate interpretation.
