What exercise suggest the Master Samael to control Anger?

Answers from the books of Samael Aun Weor

An Exercise To Control Anger

Do you feel irritated or full of anger? Are you nervous? Reflect a little; remember that anger can provoke gastric ulcers. Control anger through breathing.

Inhale the vital air very slowly (do not inhale through your mouth; inhale through your nose, keeping your mouth properly closed) mentally counting 1-2-3- 4-5-6. Hold your breath, mentally counting 1-2-3-4-5-6. Now, exhale very slowly through your mouth, mentally counting 1-2-3-4-5-6. Repeat the exercise until your anger subsides.
