I contemplated this a while ago, and although I wrote a blog on it not thought about it since.
from memory it agrees with Retro, but some points may differ slightly, but food for thought on the matter anyway?
I once heard that Enlightened beings do not produce Kamma, or negative results! I think this is rubbish! I personally think that Enlightened Beings produce Kamma, and receive its results, but the impact of the Vipakka is lesser.
I struggled with understanding Kamma for a long time, and in the end I decided that I understand some aspects of it but not other aspects so I would just have faith that it is how it is with out my understanding, then It came to me, the Kamma of Enlightened Beings is the same as anyone else’s, the only difference is that they have removed the flaws in themselves, and don’t react to the results in the same way, for instance take a lake when certain conditions in the atmosphere arise the waves of the water is rough, and when other conditions arise it is calm but it will always return to having a balanced wave level, neither two rough, or calm, but water can be removed from the lake either with a glass or other container, or evaporation. In this little analogy the waves are like the emotions, mind states, thoughts, and feelings, and although I didn’t mention them the fish are like events in our life, they come, and go, but always remain in the lake in one way or another!
I don’t believe an Enlightened being is free from the circumstances of the world, or has no intentional actions, or incapable of harming another being if the need arose (albeit a possibly rare arising) and I don’t think an Enlightened being is not going to receive the results of those actions be it positive, or negative results, but I do think an Enlightened Being deals with it differently they cope with situations in a different manner to the rest of us.
I remember the Guiding Teacher of the Isle of Man Dhamma Sangha Michael Kewley once told a story about when he asked his teacher Rewata Dhamma a question, he asked if when he became Enlightened if he would be exactly like him? Quite a good question I think! But the reply was interesting “No you will be You!” it is interesting, because it indicates that we don’t change, or that we will change, but remain us, I think the latter is true, otherwise their wouldn’t be different types of Enlightened Beings, or different stages of the path. The path so it seams is multi faceted, not one, not two, but three types of people can walk it and still achieve the same thing yet still be three different people, they have just found the best way for them, and that has led them to the same place. I am not saying each path is just as equal to another path but I am saying there are different ways to get the same result in areas, such as maths 1+2=3 but also 2+1=3 (but that is just a simple example). There was once a Tibetan monk who put stones in a bag each time a thought arose a white stone for a positive thought and a black stone for a negative thought, at the end of the day he would count up the different stones and if he thought more negative thoughts he would chastise himself but if he thought more positive thoughts he would praise himself and see how he could do better, eventually the black stones vanished from the bag at the end of the day, another monk used the Metta meditation for the same results, and another used a contemplation on the 8 Verses for training the Mind, each had the same goal each had slightly differing methods, that is the thing, if something worked once try it, it may be suited for you, but there are other options.
At the end of the day I may be right, I may be wrong, but I share this hoping I am one, or the other.
“Mendicants, these two [types of persons] defame the Tathāgata.
(The mendicants asked) What are the two [types of persons]?
(The Lord Buddha responded) The malicious, or the inwardly angry, and the one with (blind) faith or the one who holds things incorrectly.
Mendicants, these two [types of persons] defame the Tathāgata.”
