Those who live longer are said to be unteachable, so that the spirits do not dare to admonish and chastise them, for they say they know those things as well as the spirits; therefore, because they are not flexible and teachable as their youths are, the spirits desire the less to speak to them. Moreover, it is of the Lord's Providence that they do not live beyond those years, because their numbers would increase too much; for the offspring they have multiply, since famine and want do not hinder them from the procreation of offspring, as on this earth. Hence they are consociated [in marriage] in their first youth, nor do they seek anything more than the procreation of offspring. They do not so care for other delights as they are called here; they study solely their offspring.
