Gestures act as an early warning system for intent, emotion, and mood. Our body language precedes the desire of our conscious minds. Our bodies know what we want before our conscious minds do.
So it's useful to watch others' body language to know what they're thinking, desiring, and feeling. In turn, we have to learn to listen to our unconscious mind. It's telling you that you're hungry, angry, bored, happy, and content.
If you've had the experience of a strong intuition about a person, or déjà vu, or a sensation in your gut that things are not right, even though on the surface it seems fine, then you've heard your unconscious mind trying to tell you something.
Learn to regularly pay attention to your unconscious mind, not just in moments when something feels amiss. With practice, your ability to hear your unconscious quickly and accurately will improve.
A reaction is instant and driven by the beliefs of the unconscious mind. When you say or do something “without thinking,” that’s the unconscious mind making decisions in your stead.
Responses, on the other hand, are slower and based on information from both the conscious and unconscious mind. A response takes into consideration the well-being of not only you but those around you, weighs the long term effects and your core values.
