See if you can interact with the world around you without defending yourself. Watch closely your own mind and the thoughts that might arise that are defensive in nature. Also, be aware of the words you are about to speak. It is essential to understand that this practice is not about self-judgment. The mind wants to be defensive, but the heart wants to open. Just observe and note where you are coming from in any given moment. This is not an easy practice, but it will expose your fears and show you what you are hiding from.
