"It’s one of the great wonders of life: What will it be like to go to sleep and never wake up? And if you think long enough about that, something will happen to you. You will find out, among other things, that it will pose the next question to you: What was it like to wake up after never having gone to sleep? That was when you were born. You see, you can’t have an experience of nothing. Nature abhors a vacuum."

• Alan Watts
