I said I chose to be free because I don't adhere to any ancient belief. I read as much as I can, I appreciate everyone's inputs, be it ancient teachings or normal people's experiences, but I don't take anything for granted and I try to reach my own conclusions, if it's possible based on facts, not in faith, as others do here. It was a reflection on the quote I shared, as I feel we always are limited by our own human minds and the beliefs we choose to create or to follow, in order to feel comfortable inside of them. If you don't get rid of those beliefs, you don't get anywhere.
As for free will and not being bounded, I think a self-imposed obligation has nothing to do with any "Law of Karma", as this is supposed to be imposed by "the Universe", it seems. I acknowledge life-reviews, of course, in my personal search I hang around with some people who had done lots of LBL (life between lives) regressions, but I didn't get along too well with them, as they tend to make a Bible of Michael Newton's books (or at least in the group I was), again we find the same tencendy I'm referring to above... but at least some of them doubted karma as much as I do, as I believe an LBL regression gets you very close to the Truth, though it keeps being a partial view.
I'm not very keen of "lessons" either, it's like Tanguerra says, it's all a matter of freedom. Some say we are here to learn. Well, we may learn or not, it's up to us. Have I learned something from some of my past lives? Of course, or at least I want to think so. But I'm not so sure about other past lives, you can come here just to have fun too, or maybe to play what I call "a secondary role", to help others in what they want to achieve, idk, the possibilities are endless...
Free will doesn't mean you can do whatever you want, I think you might be mistaking the concept of "liberty" with "license". We live in a world with other people, there are always limits to the things we can do, maybe that's one of the most important "lessons" we find in reincarnation. There's no excuse to cause suffering in others, and being able to give up your "spiritual rights" or your own life to prevent that suffering is something only a few achieve. So, if I think I have free will, that means there's no one out there (God or Universe) telling me what to do, but this doesn't mean the Universe is chaotic and anarchic. I'm here for the experience, and to understand why such rules are necessary (I said rules but I believe the One Rule is Love). When we cross to the other side, I believe we all are perfectly aware of the point in which we are, and just like you look for a new job if you lose one or get bored, you'll go for new goals, depending on what you want to do next. This depends only on us, no one can forces us to do something we don't feel ready to, and of course your past experiences don't determine anything. They just change you... or not.
