If you ever read any of the currently most popular theories about reincarnation (such as Desiny/Journey of souls by Michael Newton), they state that the general trend of Earth is development toward a higher energy frequency. Since souls usually find a place to incarnate that matches their frequency somewhat, you are more likely to have been reaincarnated in the historical past than in the historical future – even though such cases also exist for several reasons.
Is development toward a higher vibration evident? It is hard to see, but i’d say it is. Prostesting against war, social rights movements, and most of all, people’s respectful treatment of children (look into phychohistory) have been something tha history never before knew. Not to mention the advances in technology and medicne, that have dramatically increased life expectancy, standard, and quality all over the world. I am not sayign the world is perfect; what i am saying it is objectively a better place to live, on average,t han it was a hundred, or a thousand years ago.
As for my personal experience, i have seen many things that could lead me to believe in reincarnation, but i remain, as about all things, skeptical. Since very early childhood, i have “rebembered” one particular life, of a French officer in the late 1400s, who led a violent and ambitious life and died a gruesome torturous death. I vaguely “remember” a few other past lives, but this one has influenced and intrugued me most.
