Paradise Lost, Book I, Lines 254-263

The mind is its own place, and in it self
Can make a Heav’n of Hell, a Hell of Heav’n.
What matter where, if I be still the same,
And what I should be, all but less then hee
Whom Thunder hath made greater? Here at least
We shall be free; th’ Almighty hath not built
Here for his envy, will not drive us hence:
Here we may reign secure, and in my choyce
To reign is worth ambition though in Hell:
Better to reign in Hell, then serve in Heav’n.
