Violence perpetuated by humans springs from the ego and is based on insecurity. The insecurity in turn is a product of a wrong understanding (Avidya) of our relationship with our environment. We are not two separate entities competing with each other for survival. We are in fact two halves which together constitute the indivisible SELF.
Once we realise this central truth all aspects of existence would become a wonderful spectacle, a glorious dance. Similarities will then attract us to each other and differences will enrich us.
