"Can anyone give me some clarification as to what the above Sutta is saying? In the first paragraph it seems to say that you can not wipe out results of karma in this life or in further states. In subsequent paragraphs it seems to imply that results of action can be eliminated by this practice."
I think the first paragraph is a general statement that applies to regular worldlings while the subsequent paragraphs are more focused on a noble disciple. The case of Angulimala would clarify this:
"Bear it, brahmin! Bear it, brahmin! you are experiencing here and now the result of deeds because of which you might have been tortured in hell for many years, for many hundreds of years, for many thousands of years" ~~ MN 86 ~~ (http://www.accesstoinsight.org/tipitaka ... .than.html
