there's a divinity

Sir, in my heart there was a kind of fighting,
That would not let me sleep: methought I lay
Worse than the mutines in the bilboes. Rashly,
And praised be rashness for it, let us know,
Our indiscretion sometimes serves us well,
When our deep plots do pall: and that should teach us
There’s a divinity that shapes our ends,
Rough-hew them how we will,—

Hamlet 5.2.5-11
