This may be nitpicking, but I have a question regarding this term. In Realizing Genjokoan, on p. 111, Shohaku Okumura defines this as "the process of body and mind arising (being born) and perishing (dying) over and over again, moment by moment."

I'm just wondering if this arising and perishing is meant to be a solid, continuous process, or one more like a film running at a million frames a second, where each moment is a fixed moment that, through its motion, gives the illusion of movement.
