It is true that one acts on the other . Its obvious that one acts on the other . But it would help to demarcate between the arising and falling away of each of these aggregates.
That would be a mistake, because they can overlap, and they are not sequential.
They can vary in intensity, and are co-dependent.
While we can describe the different processes, separating and demarcating is neither possible nor necessary.
Avijja (Ignorance) is the root of the problem
From Avijja arises Mental Formations (Mental Kamma)
From Mental Formations arises Defiled Perceptions and Defiled Consciousness.
Personally, I don't think, in ordinary everyday parlance, you can speak of all mental formations, perceptions and consciousness as being 'defiled'.
It's a very strong term to describe, for example, the processes you go though when witnessing something beautiful (by definition) happening, like a flower blooming, or a dragonfly emerging form its pupaeic shell...
Both, to be sure, are indicators of impermanence, but I cannot consider them as 'defiled'...
I think this is how the mind should be trained. First develop Wisdom which cuts the process of formation of Mental Kamma/Defiled Perception/Defiled Conciousness.
This I can see as being valid....
Feelings are that - Pleasant/Unpleasant depending on the situation. I think Wisdom has no role here.
On the contrary. I believe it is of essential and vital importance here.
Wisdom cannot control the type of feelings you feel. When there is a Bad odour there is a Bad odour, everyone would feel that there is a Bad odour. It is how you react to the bad odour which is important.
Which is where Wisdom is most certainly required; to ensure the discernment is not clouded by the conditions leading to Suffering.
Please Correct me If am wrong in my analysis anywhere.
Not wrong; mistaken. But there again, that is just my perception.
I may well be completely incorrect.....
