I read this thread and all the posts and I also think that it might be possible to alter your past. Yes we can't change the record books but we can change ourselves and how the world sees us. And also because if LoA makes all things possible so technically speaking altering past is not outside the boundaries of manifestation.
As far as record books are concerned let us take and example which will clear that we don't need to change the record books. For example if some college age student wishes had she worked hard in her school years she would have got higher grades. Now if she visualizes hard that she actually got A++ in her school years she still can't erase that from her record sheet. But she doesn't need to because why she is visualizing higher marks is more important. May be for getting a course of choice or college of choice in her present. So the Universe will create that reality for her in her present tense and she may get admission into a college of her choice. If there is some test to get admitted into the college she will remember everything during the test because her visualized reality will remind her that she was indeed a hard working student and she knows everything to get into this college. So in essence she has changed her past.
And this technique is also useful in those cases where there are no record books to keep or update like erasing some bad memories like a trauma or something like that.

But now I come to the point. How will a person manifest a dead person alive? No I am not going to try this but just because of curiosity I am asking. Suppose somebody lost a loved one a few years ago because of some accident. Now they visualize that the accident never happened. So how will this thing manifest? Or is it better to leave some stones unturned because we may not know the consequences? One possible outcome in my views could be again why we want that beloved person back. May be we are missing their company and God may send some other person with similar qualities in our lives.
