Manifestation takes place in time and space. The sun, the moon, and the planets all have their influence. Morning, noon, evening, night, and every hour of the day each have their special influence too. The children of one father and one mother are very different from each other in height, in breadth, in appearance, in every way, because they are born at different times. If one brother is fifteen years old and the other five, the difference between them will be very great. Twins are very much alike because there is little difference in the time of their birth. Lambs are all much alike because they are born in the same season; and fishes of the same kind are almost exactly alike because thousands of them are produced at the same moment.
