As far as mental development is concerned, we should never be complacent. We can develop our minds infinitely - there is no limitation.
Dalai Lama"The true essence of humankind is kindness. There are other qualities which come from education or knowledge, but it is essential, if one wishes to be a genuine human being and impart satisfying meaning to one's existence, to have a good heart."
Dalai LamaAlthough we are all the same in not wanting problems and wanting a peaceful life, we tend to create a lot of problems for ourselves. Encountering those problems, anger develops and overwhelms our mind, which leads to violence. A good way to counter this and to work for a more peaceful world is to develop concern for others. Then our anger, jealousy and other destructive emotions will naturally weaken and diminish.
