Craving & Attachment

Sankhara parama dukkha--All compounding is thoroughly unsatisfactory. That means that involvement which has reached the point of craving and attachment is nothing but misery. Without this kind of compounding there is freedom from the misery of the unsatisfactory condition. It is this very compounding that is referred to as the Wheel of Samsara, that cyclic process with its three aspects; defilements, action based on those defilements, and results of the action, The defilements, producing satisfaction with the result of our actions (or karmas),  prompt us to further action--and so the cycle of defilements, action and fruit of action goes on endlessly. It is this process that is called compounding; and it is this endlessly repeated process of compounding that is referred to in the statement that all compounding is thoroughly unsatisfactory.
