In this interesting transcript of a teaching that Lama Zopa gave, he talks about the five beneficial attitudes of kindness, rejoicing, tolerance, contentment and forgivenss that can be taught to children. He mentions:
These five very basic attitudes are very important to keep in one’s mind. This is the cause of inner peace and happiness for your child, also to give peace and happiness in everyday life to others. In this way, wherever your child is, in whatever part of the world, he or she still brings happiness to so many sentient beings, human beings, animals, and all other beings.
