Before parents one must not utter jokes, must not show restlessness, must not show anger or temper. Before mother or father, a child must bow down low, and stand up in their presence, and must not take a seat until they order him to sit. If the householder has food and drink and clothes without first seeing that his mother and his father, his children, his wife, and the poor, are supplied, he is committing a sin. The mother and the father are the causes of this body; so a man must undergo a thousand troubles in order to do good to them.
