As the Time Draws Nigh by Walt Whitman Lyrics

As the time draws nigh glooming a cloud,
A dread beyond of I know not what darkens me.

I shall go forth,
I shall traverse the States awhile, but I cannot tell whither or how long,
Perhaps soon some day or night while I am singing my voice will
        suddenly cease.

O book, O chants! must all then amount to but this?
Must we barely arrive at this beginning of us? —and yet it is
         enough, O soul;
O soul, we have positively appear'd—that is enough.
