Sonnet: Now shall the certain purpose of my soul

Now shall the certain purpose of my soul
By blind and empty things controlled be,
And mine audacious course to that far goal
Fall short, confessing mere mortality.
Limbs shall have movement and ignore their living,
Brain wit, that he his quickness may deny.
My promised hope forswears in act of giving,
Time eats me up and makes my words a lie.

And mine unbounded dream has found a bar,
And I must worst deceit of best things bear.
Now dawn’s but daybreak, seas but waters are,
Night darkness only, all wide heaven just air:
And you to whom these fourteen lines I tell,
My beauty, my desire: but not my love as well.
