There are two types of traveller. Those who know where they are travelling to, and those who do not know where they are coming from or where they are going. When these open their eyes, they only realize that they are in this ship, that they come from somewhere and that they are in a ship which is moving and is going somewhere. There are many people like this living in the world today. They are so absorbed in their everyday activity that they are ignorant of where they come from and where they are going.
