Pain in life is inevitable but suffering is not. Pain is what the world does to you, suffering is what you do to yourself [by the way you think about the 'pain' you receive].

Know all things to be like this: As an echo that derives From music, sounds, and weeping, Yet in that echo is no melody. Know all things to be like this: As a magician makes illusions Of horses, oxen, carts and other things, Nothing is as it appears.

Surely if living creatures saw the results of all their evil deeds, they would turn away from them in disgust. But selfhood blinds them, and they cling to their obnoxious desires. They crave pleasure for themselves and they cause pain to others; when death destroys their individuality, they find no peace; their thirst for existence abides and their selfhood reappears in new births. Thus they continue to move in the coil and can find no escape from the hell of their own making.
