... not meaning the Arrivals terminal at the airport, or alternately the Departures edifice at the same locus or terminus ...
But something else.
("That is not I meant at all.")
Hold on a second. Try on for size, color, and style these oft-quoted lines, by T.S. Eliot, in "Little Gidding":
We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.
the unknown, unremembered gate
When the last of earth left to discover
Is that which was the beginning;
At the source of the longest river
The voice of the hidden waterfall
And the children in the apple-tree
