from “The Nature of Psyche”, Session 771:
In some historical periods it was desirable in practical terms that a man have many wives, so that if he died in battle his seed might be planted in many wombs — particularly in times when diseases struck men and women down often in young adulthood.
When physical conditions are adverse, such social traditions have often emerged. In times of overpopulation, so-called homosexual and lesbian tendencies come to the surface — but also there is the tendency to express love in other than physical ways, and the emergence of large social issues and challenges into which men and women can throw their energies. There are “lost” portions of the Bible having to do with sexuality, and with Christ’s beliefs concerning it, that were considered blasphemous and did not come down to you through history.
