We are its children, its offspring, and therefore all that there is of boundless space is we ourselves in our inmost. Out of the invisible into the visible, like the growth of a plant, comes man, the man-plant of eternity. Such in brief is the history of man, the man-plant of the ages. A human seed comes from the ethereal worlds and is the laya-center through which streams from and builds up from the interior worlds the body to be, cell by cell. This seed grows into the physical body and, as it grows, incarnation of the human energies takes place concordantly, coordinately, and progressively, until maturity is reached, and at that point you see the full-grown man and more or less fully incarnated human soul.
Man is a complex and compound entity.
When these seven different degrees or grades are cooperating in vital activity then you have a complete man, a fully living man. It is not wholly mortal, because its instincts, its movements, the operations of itself, are in a sense above purely mortal things of matter. Man has holy loves, aspirations, hope, and vision. The pane of glass is the vehicle or carrier or bearer or transmitter of this wondrous quality or force streaming from the sun above. The human soul is like this pane of glass, letting through as much of the spirit, of the golden sunlight of the spirit, as its evolutionary development enables it to do.
