The wish to build a tower into heaven and to make a name is the ego's whole ambition, the attempt to reach salvation by construction and to secure a separate self against loss. Behind every stone is the fear named plainly at the end: the dread of being scattered, of dissolving back into the union the mind believes it has escaped. So it labors to prove it is real and set apart.
Heaven is not climbed to by effort, for it is already the mind's true home. The name the ego seeks to make is the very belief in separation it is trying to defend. Peace comes not from building higher but from laying the project down and remembering that the self it feared to lose was never in danger.
City: the ordered structure the ego builds to house a separate self, the defense of specialness made solid.
Tower: the attempt to reach salvation by effort and height, the mind's striving to climb to what it already is.
Name: the identity of the separated self the ego labors to establish and preserve against dissolution.
