Is there a cycle of rebirth?

Do you not understand that what you believe you are going to be out here [the world of Spirits] is largely determinative of what you will be? 

Those who do not believe in rebirth cannot forever escape the rhythm of rebirth, but they hold on to their belief until the tide of rhythm sweeps them along with it and forces them into gross matter again, into which they go quite unprepared, carrying with them almost no memory of their life out here. 

They carried out here the memory of the earth life because they expected so to carry it.
