'Children are always hotter than their parents'.

This is true only with Jesus and Buddha that i know of. But you can see how confusing such teaching is tozenji. For a child to be raised thinking he is hotter than his parents, it is very hard not to make them vain. Such not at all a useful teaching though real when it comes to children who are buddhas. Although I must say i see one benefit: stay away from fucking your child because the general word is that he or she is hotter than you. And respect your child's wisdom. Something the christians are working on right now.
