Did I ever tell You definition of reincarnation?

Insanity  REINCARNATION  is:
Doing the same thing over and over again
and expecting different results.

Someone can argue: "I'm not doing same thing over and over again; in one life I was that, in other I was this ... " and so on.
But technically, YOU WERE AND YOU ARE JUST POWERING THE MATRIX. (and you know what kind of energy is powering Matrix, don't you?)

You can't DO anything here on 3D.
You can do something by refusing any other incarnations, by avoiding Wihte Light Trap.
That will put You on higher level than 3D, and then You can do something.
