The boundaries of a Being are marked by its [[systole and diastole]], and these are the gateways to other Natures. A Being [[changing]] past its systole becomes a lesser type of Being, a Being of a lesser Nature. A Being changing past its diastole becomes a Being of a greater Nature. (In no case is it possible for a Being to become a different Being.) In the case of [[Humanity]], this latter process is called [[Apotheosis]], and it is whereby you and your spouse put off your Human Nature and take on Talon Nature.
