One so seriously considers one’s wife to be his own that he sometimes kills himself for her or kills others, including even his parents or his spiritual master or teacher. Therefore if one can give up his attachment to such a wife, he conquers the Supreme Personality of Godhead, who is never conquered by anyone.
