I guess that in the spirit world, it is all about learning. But there is a lot of love in the spirit world, more love than you could ever dream of. It is the kind of overwhelming love that makes you burst out crying of its intensity and beauty.
It seems to me that my whole life on earth is a learning experience for my soul which is happy to experience any pain (physical and emotional) that can bring the desired soul growth.
Also, from experience with the spirit world, I know that it was my own desire (as a soul) to come as a human being and live such a (hard) life on earth.
