William Butler Yeats Quote

My Soul. Such fullness in that quarter overflows
And falls into the basin of the mind
That man is stricken deaf and dumb and blind,
For intellect no longer knows
Is from the Ought, or knower from the Known —
That is to say, ascends to Heaven;
Only the dead can be forgiven;
But when I think of that my tongue's a stone.
