B DUKKHA CAGE

From this way of expressing Lord Buddha's teachings, to be content with conditioned existence is to be content within a cage. Dukkha -- a lack of ease, a lack of satisfaction, not being able to obtain or enjoy that which is sought for, not being able to avoid or ignore that which one is averse to... something both deeper and more subtle than simple 'pain', 'stress', or 'suffering' as it is present within attachment to all things, whether that attachment brings happiness or otherwise -- will always come. The craving for materials things is a problem, of course, as anyone can realise. The basic craving to exist, to survive, to consume the sustenance provided in our environment, even this itself brings dukkha. And, from within the framework of conditioned existence, there is no solution.
This is why Lord Buddha taught a path that goes beyond conditioned existence. So, to summarise, what I am saying is that you are considering an important realisation about an aspect of our worldly existence, but one which does not go beyond that.
