The idea is that suppressed emotions cause thoughts. Strong surfacing emotions will usually create a tide of thoughts which can impact you in a number of ways. Thoughts are always pointing you in the direction of healing and by getting in touch with your emotions and letting them go, you will begin to quieten your mind. Emotional release will help you in letting go of all thoughts related to that specific emotion so by releasing anger you will release angry thoughts. The very structure of the thoughts will also tell you about what emotion needs to be cleared.
