"Thus the great epoch in the development of Creation had come: on one side, in the Gross Material World, stood the most highly evolved animal, destined to provide the gross material body as a vessel for the coming human being; on the other side, in the Ethereal World, stood the developed human soul, waiting to unite with the gross material vessel, and thereby give everything of gross matter a further impetus for spiritualization. Now, when an act of procreation took place between the noblest pair of these highly developed animals, at the moment of incarnation not an animal soul was incarnated as hitherto, but instead, the waiting human soul bearing within it the immortal spirit spark."
