Of course, meditation helps in managing your anger. Meditation helps us to rid ourselves of emotional conflict, inner discord and psychological tension. It completely purifies the mind and frees it from unconscious obstructions. Here, I would prescribe the Brahmakumaris Raja Yoga Meditation. They have 7 days introductory free course and then you can proceed to the meditation at the Brahmakumaris Centre free of cost. Their centres are widely spread across the country as well as internationally.
However, I would rather suggest you to work out on your lifestyle and attitude and thoughts patterns in order to know the causes and manage your anger. Also do chintan everyday on your happiness and self-satisfaction (contentment) - absence of these two things irritates our nervous system and cause anger on little things even.
