All things subject to birth are destined to disappear. If you question your very birth, you might discover eventually that you have never been born and that your birth is no more than a hypnotizing description of reality and not reality itself - an imaginative ideological concept that you believe to be true.
To not die and live forever you have not to be born, that means to stop believing you were ever born and realize steadfastly that birth like death is only propaganda - pure superstition.
