As the Arab racer needs not the whip,
So you will not need to fear
When on your journey you have started.
When purified are your soul and body,
You will not fear the fires of hell.
Throw pure gold into the fire;
If it contains no alloy, what is there to burn?
Mahmūd Shabistarī
The mind is its own place, and in itself,
Can make a Heaven of Hell, a Hell of Heaven.
John Milton
