I have known people actually plan for their next life through reading and learning something new, that they hope will be useful. If that is their belief.... then so be it.
I have amazingly known people excuse a bad relationship with someone as a problm with them in a previous incarnation. I think they need to learn to live this one (even if that is true)and stop making excuses.
I do believe we have a soul and that life is eternal. Too many things in life have happened for me not to believe that. I cannot believe that humans and the world are here just by acccident and that there is no point to everything in the world. It is all far too complex and beautifully made for that
It would be nice to think that all our friends and family that have passed away would be there waiting for us when we go. I think I will take a shovel with me when it is my time to go just in case it is a load of rubbish. It would just be my luck to come back as a Dung Beetle.
