And may not be performed by thyself:
For that which thou hast sworn to do amiss
Is not amiss when it is truly done;
And being not done, where doing tends to ill,
The truth is then most done not doing it:
The better act of purposes mistook
Is to mistake again; though indirect,
Yet indirection thereby grows direct,
And falsehood falsehood cures, as fire cools fire
Within the scorched veins of one new-burn'd.
It is religion that doth make vows kept;
But thou hast sworn against religion,
By what thou swear'st against the thing thou swear'st;
And mak'st an oath the surety for thy truth
Against an oath: the truth thou art unsure
To swear, swears only not to be forsworn;
Else what a mockery should it be to swear!
But thou dost swear only to be forsworn;
And most forsworn, to keep what thou dost swear.
Therefore thy latter vows against thy first
Is in thyself rebellion to thyself;
And better conquest never canst thou make
Than arm thy constant and thy nobler parts
Against these giddy loose suggestions:
Upon which better part our prayers come in,
If thou vouchsafe them; but if not, then know
The peril of our curses fight on thee,
So heavy as thou shalt not shake them off,
But in despair die under the black weight.
