All non-linear processes exhibit what is called scale invariance, meaning that the behavior of the process on any one scale is similar to its behavior on smaller or larger scales. To understand, say, the large-scale pattern of a particular non-linear process, one need only focus on its behavior on a smaller scale that is easier to observe, and one will see the same pattern at work. In the case of kamma, one need only focus on the process of kamma in the immediate present, in the course of developing heightened skillfulness, and the large-scale issues over the expanses of space and time will become clear as one gains release from them.
In terms of focus, the principle of scale invariance means that the complexities of kamma can be mastered by giving total attention to phenomena in and of themselves in the immediate present. These phenomena are then analyzed in terms of the four noble truths, the terms used in observing and directing the experience of developing the qualities of skillful action. The most immediate skillful kamma that can be observed on this level is the mastery of the very same mental qualities that are supporting this refined level of focus and analysis: mindfulness, concentration, and discernment, together with the more basic qualities on which they are based. Thus, these mental qualities act not only as supports to the focus and analysis, but also as their object. Ultimately, discernment becomes so refined that the focus and analysis take as their object the act of focusing and analyzing, in and of themselves. The cycle of action then short-circuits as it reaches culmination, and Unbinding occurs.
