So, I had been reading Ven. Thanissaro's "Wings to Awakening" anthology, and in the section on Kamma, there is one thing I have difficulty wrapping my mind around; "The truth of the Buddha's understanding of the processes of kamma — as informed by this/that conditionality, dependent co-arising, and the four noble truths — was proven by the knowledge of Unbinding that followed immediately on his mastery of the fourth type of kamma. He found that when skillfulness is intentionally brought to a point of full consummation, as expressed in the direct awareness of this/that conditionality, it leads to a state of non-action, or non-fashioning, that forms the threshold to a level of consciousness in which all experience of the cosmos has fallen away. When one's experience of the cosmos resumes after the experience of Awakening, one sees clearly that it is composed entirely of the results of old kamma; with no new kamma being added to the process, all experience of the cosmos will eventually run out — or, in the words of the texts [§225], "will grow cold right here." This discovery proved the basic premise that kamma not only plays a role in shaping experience of the cosmos, it plays the primary role. If this were not so, then even when kamma was ended there would still remain the types of experience that came from other sources. But because no experience of the cosmos remained when all present kamma disbanded, and none would resume after all old kamma ran out, kamma would have to be the necessary factor accounting for all such experience. This fact implies that even the limiting factors that one encounters in terms of sights, sounds, etc., are actually the fruit of past kamma in thought, word, and deed — committed not only in this, but also in many preceding lifetimes. Thus, even though the Buddha's development of the fourth type of kamma focused on the present moment, the resulting Awakening gave insights that encompassed not only the present but also all of time."
What I understand this to mean is that, after his awakening, all his further actions were composed or rather caused by his old Kamma. However, how was it so that he could still be acting in the world, yet not creating any new Kamma? Certainly his actions had very
big effects during his period of teaching. Was it simply the fact that he was, somehow, acting yet remaining unattached to his actions? This would be my best understanding of how it was so, but I feel like I'm missing something here...
Looking forward to some good discussion, and some better understanding.
