Every child has to disobey the father. Unless a child disobeys the father he never becomes mature. It is nothing, original, it is very simple and natural. It is very psychological. There comes an age when every child has to say NO to the parents. If he does not say no to the parents he will not have a spine; he will be spineless. If he cannot say no to the parents, he will be a slave his whole life. He will never attain to individuality.
