So then, just in the same way as you don't know--you don't focus your attention--on how you make your thyroid gland function, so in the same way, you don't have any attention focused on how you shine the sun. So then, let me connect this with the problem of birth and death, which puzzles people enormously of course. Because, in order to understand what the self is, you have to remember that it doesn't need to remember anything,just as you don't need to know how you work your thyroid gland.
So then, when you die, you're not going to have to put up with everlasting non-existance, because that's not an experience. A lot of people are afraid that when they die, they're going to be locked up in a dark room forever, and sort of undergo that. But one of the interesting things in the world is--this is a yoga, this is a realization--try and imagine what it will be like to go to sleep and never wake up. Think about that. Children think about it. 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, it will pose the next question to you. What was it like to wake up after having never gone to sleep? That was when you were born.
