I believe that the very purpose of our life is to seek happiness. That is clear. Whether one believes in religion or not, whether one believes in this religion or that religion, we all are seeking something better in life. So, I think, the very motion of our life is towards happiness.
Compassion and love constitute non-violence in action. They are the source of all spiritual qualities: forgiveness, tolerance, all the virtues. They give meaning to our activities and makes them constructive. There is nothing amazing about being rich or highly educated; only when the individual has a warm heart do these attributes become worthwhile.
If you can cultivate the right attitude, your enemies are your best spiritual teachers because their presence provides you with the opportunity to enhance and develop tolerance, patience and understanding.
