Control your breath. It has been said that those who have the ability to control their breath have the ability to control their life. In many aspects, this statement is very true. Look back to a time when you lost control. What happened to your breathing pattern? In anger, your breath became short and quick. If you control your breath, you can understand and change your negative emotions.
Either in a quiet space or during meditation, practice following your breathing. As you take a breath in (through your nose), feel the air enter your body and go deep into your lungs. As it hits the deepest part of your lungs, feel it slowly leave your body (through your mouth) and release any and all tension.
