“Seth material” search engine (Jane Roberts)

Concerning the overpopulation problem, remember that more than physical mechanisms are involved. The problem will be solved by mankind indeed; but mankind is composed of reincarnational entities. It is quite within the probabilities that the statistics will reverse themselves and that for no reason that scientists can discover, children are born stillborn, as in a mass epidemic, and that entities simply refuse to inhabit the bodies made for them. The bodies then remaining empty to decay unused. (What a grim situation, I thought.)

When you think in terms of mankind solving its own problems, remember that reincarnation is involved, and not a group of persons in existence for only a particular time. When the personality is thoroughly ready to leave the body, nothing, including transplants, will keep it within the body. And if personalities refuse to inhabit a new body, then no science will be able to give life to the newly formed but uninhabited body.
