Psychologically speaking it is not helpful to think of forms as anything but convenient signs. Yeah they exist for practical purposes, but they actually don’t. Psychologically speaking (again) we need to get away from thinking that there is ever a split between “things” and “process”. Ultimately it’s all relativistic. The one Absolute Truth is that everything is relativistic... of course most people (philosophers?) reject that as a trivial contradiction, but Mahayana does some tricks (apparently—who am I, Wittgenstein?) which makes this seeming contradiction just work.
At the end of the day our natural intuitions are wrong. They were more towards Aristotle’s view. So we have to actively do things like analyze or meditate in order to see reality for what it truly is. In order to rid ourselves of clinging.
