Responsibility fulfilled leads to peace. And vice-versa.
In daily life, we have many responsibilities like towards family, work colleagues, friends, etc. When we avoid our responsibilities, suddenly the donkeys on our back start piling up, the tension starts building up. What do we have to do ? We have to throw the donkey off our back, or in other words fulfill the responsibility. Then, suddenly we feel light. We are without the weight of the donkeys. Obviously we will now be light. Feeling light means to be at peace. Be responsible, peace follows.
Responsible people get peace !
