Another factor involved in violence is chemical imbalance. When there is an imbalance of glandular secretions in the body, people become violent. Every endocrine gland has its specific functions. A harmonious functioning of these glands keeps a man balanced. Any imbalance, in the former results in an imbalance in the latter.
Meditation can restore the lost balance.
Such an understanding is duly backed by the findings of modern biochemistry. Since violence can be ascribed to hormonal imbalances in the body, meditation turns out to be their best therapy. Occasionally we come across cases of motiveless violence. When questioned, the agents of such violence simply say that they resort to violence for no reason other than deriving joy. It requires alternate breathing through the two nostrils - inhaling through the left and exhaling through the right nostril and then in the reverse order, and repetition of the cycle.
