The first ship to sail to America had to discover the way, and it took very long; but afterwards a course was mapped out, the way became known, and ships made the journey in a shorter time. America is the goal, and the ship is the means of getting there. In the same way religion is a means of getting to the goal, but it is not the goal itself. It is possible to reach the goal without a ship, but it is quicker and easier to reach it with a ship.
