Khomeini advises Rajai

Khomeini: Yesterday you were prime minister; the day before yesterday, you were minister; and before that you were a teacher. And before that you were a student. And from now on, it is not clear [what will happen]: You may go out of here and God forbids… or even right now a bomb might explode here 0:29and finish us all. When it is like this, then why should people be any different before and after presidency. What is this presidency?
