Yes! Even though we can talk about “impermanence/decay” of external things (which is also true), the main point is the anicca nature of the panca upadana khanda.
- Those rupas that the mind makes (“cakkhu vinneyya rupa“) are of the anicca nature. Those are the types of rupa that we hope to attain/acquire. Even if such a material rupa is acquired, we cannot keep it forever, or even until death, most of the time. for example, we like to eat tasty food, and most of the time, we can accomplish that. (But in reality, all that effort was in vain because the “tastiness” is an illusion!) Furthermore, if we want more of that food, we have to do it all over, too. There are many implications to contemplate.
- Thus, our efforts (sankhara) are of the anicca nature (pointless, fruitless); our expectations for such rupa (vinnana) are of the anicca nature.
P.S. The mind-made “cakkhu vinneyya rupa” is made with the “distorted sanna.” Of course, Arahants do not get to that step, even though they also get the “distorted sanna” (of tasty food, for example.)
