But who is that on the other side of you?

Ah finalmente encontrei a passagem da The Waste Land onde o Eliot fala das alucinações extracampicas:

Who is the third who walks always beside you?
When I count, there are only you and I together
But when I look ahead up the white road
There is always another one walking beside you
Gliding wrapt in a brown mantle, hooded
I do not know whether a man or a woman.
-But who is that on the other side of you?
