First, give up all impure impulses and cultivate the pure ones. After this, try step by step to give up even these and render the mind objectless, Nirvishaya. Peace thus obtained is effulgent, blissful and associated with Wisdom. It is indeed the experience of God himself. Peace is the key quality that everyone of you must aspire to achieve. The aspirant who wants to attain this peace has to constantly practise a virtuous life, overcoming all the initial obstacles. Peace is like a mountain of rock. It can stand up against the continuous floods of temptation against evil. This Prasanthi (supreme peace) need not be sought anywhere outside. It emanates from the inner consciousness itself. It is the very basis of the urge towards liberation. 

-Divine Discourse,  Prasanthi Vahini.

Nature wants us to react, to turn blow-for-blow, cheating for cheating, lie for lie, to hit with all our might. 
It requires Super Divine power to not hit back, to keep control, to be unattached. - Baba
