Its likely if i have to repeat life then ill be sent to another 3d planet, if higher self permits, my choice would be a technologically advanced planet with interstellar travel. Otherwise whatever is best for me will happen. When im back in 5d i believe i will remember everything i did prior to incarnating here.
You see yourself isolated from higher self, what if you are on 5D and you are closer to higher self, then your decision would be truly yours- there won't be two of you, this is predator talking when you imply i will ask my higher self, you want ask no one we because that person would stay within your body here and will die with it. Your soul doesn't care where it is learning it's lessons because STO doesn't have wishes it only has knowledge of what is, and saying that you want to go to some high tech planet is wishful thinking done we know all by what, this is concentrating on external and not on that what is important - internal growth. I would rather go with someone who can give me suffering, pain and tears because I learn more and i earn my will, but saying that i can feel also that part of me resisting saying that because it knows it isn't easy but it isn't me and it isn't time to close eyes on reality and is time to put aside that childish thinking.
Your questions seem to be patterned after a "game" analogy, where if you lose (fail at the work) you get punished (sent back to some square?) and maybe have to start over (from square one?).
I see it as a truth, you start again but the problem is perception how do you see it. When Laura asked C's if that is a punishment they only said it is learning, the problem is with our beliefs what is wrong what is right, there isn't right and wrong, and someone saying that doesn't really know what is to be in position of person that does "wrong" choice but this world is full of judgments, no one respects each other choices.
Do you go to the 5th density when you die and look back over why you failed and then try and learn from those experiences? Or do you go back into the whole cycle from the beginning? either as if you never began the work or right back to 1st density. Is failure "punished" in a sense or is it part of a natural cycle which is for some just part and parcel of the struggle and yet more opportunity to learn.
When C's said about soul smashing I think it has to do if you act against your polarity which is to big shock for soul to handle because maybe it's to sudden change in polarity and wave magnifies that, but it's probably different for every person that is someone will incarnate in other planet, some will do cycle again, some will be smashed, some will go to 4D and die and some want die, others can be hit by truck tomorrow, you see how it's pointless to think about it. What happens you can really do nothing about that, you can do only best and be best that you can and ask yourself is that the best thing you can do, if you "fail" or succeed you are still something special, and i know from personal experience that thinking about the future can be toxic, it's even stupid to do that because it never ends like you think it will, it's better to do what you can do - work on yourself and live now because it's the only thing you have and can do. If it is a problem of will and you don't have it, do it again, and again, and again until you make it, if you need to do it 1000 times do it, every problem I found with myself is in that thoughts that say to you you can't do it or others do that kill you spiritually and limit you and it isn't truth, it's all matter of belief in you, there's no limits in the end. If we all knew real consequences of our action we would surly be 100 per cent in work, talking and experiencing are two sides and whenever I get a sleep I think about it, it isn't so much about fear - it's about knowing about yourself, but there is always some fear and fear sometimes can help, and everyone fears except if he isn't a psychopath or spiritually advanced . G. said (I remember when O. asked him) about reincarnation that it's better to not know about it because you will give much more to work then not knowing about it. I don't know what else to say you slowone, you have to find what you ask in yourself and think about it, good luck.
