Many problems are created in our world today because people do not engage in what will actually lead them onto a path that benefits them and brings happiness. From the time we open our eyes in the morning until we sleep at night, if we can pass the whole day with a kind-hearted mind and cheerful face, on good terms with people and talking pleasantly to them, our mind will be relaxed when we go to sleep at night. On the other hand, if we spend the day making others upset, if we fight, and even if we win, when we are going off to sleep at night we will have regrets and our mind will not be at ease.  ~ 17th Karmapa
