Can the change due to impermanence be considered intelligent? What is the nature of the change due to impermanence ,is it just a random change or intelligent change ?,are the actions resulting from it considered right action or that depends on the degree of identification that the impermanent person/thing is having towards another person/thing?.

The more I watch it I see that sometimes this change or flux is not just random and is intelligent.All the changes happening inside the body and mind do not require a doer but are intelligent.Can the nature or the behavior of the change be also recognized ?.
Buddhism isn't overly concerned with the source or cause of impermanence. The Buddhist problematic is that the mind fixates on permanence — on wanting things to be a certain way, always — and that fixation causes misery of various sorts when things do change (as they inevitably will).

I'm not certain what thought or insight is bubbling around behind this question (perhaps it hasn't made itself clear even to you, yet), but you should be aware that fixating on impermanence can be just as problematic as fixating on anything else. Who or what are you trying to ascribe intelligence to?
