Lord Byron Quote

There is no power in holy men,
Nor charm in prayer, nor purifying form
Of penitence, nor outward look, nor fast,
Nor agony—nor, greater than all these,
The innate tortures of that deep despair,
Which is remorse without the fear of hell,
But all in all sufficient to itself
Would make a hell of heaven,—can exorcise
From out the unbounded spirit the quick sense
Of its own sins, wrongs, sufferance, and revenge
Upon itself; there is no future pang
Can deal that justice on the self—condemn'd
He deals on his own soul.

Act III, scene i - Manfred (1817)
