I have heard that in Russia an experiment is to take place for the first human head transplant, very interesting stuff, thats as close to body swap as I can think of, but don't feel that way honestly.
I remember walking through the city yesterday and overheard a woman saying that she felt worthless, I was extremely pained by this, it hurt to hear someone felt that way, and its no different here.
Make the changes on the inside, not the outside. I know of an old Buddhist story of the man who had a dilemma, he wanted to be able to walk comfortably on the ground as he had no shoes, so he covered the earth with leather.
The 2nd Buddha Atisha walks by and asks him why he is doing this, the man said that covering the whole earth would mean that I can walk anywhere without it hurting. But this puzzled Atisha, and he said, why not just cover your feet instead?
The same is very true to our human existence, trying to control our external conditions and making it suit our needs. This is a very pointless and not to mention tiring task, instead cover your soul with leather instead!
