57:  In the co-ordination of the Monadic, Atmic and Buddhic vehicles of the Heavenly Man, the vehicles of spiritual life, the higher esoteric correspondence to the prana flowing through the lower reflection, the etheric physical body, the point of synthesis is always on the atomic subplane, and the six merge and become the seventh.  In this solar system the plane of synthesis is not included in the evolutionary scheme.  It is the plane of gathering in and of pralaya.  In the earlier system the fourth aetheric was in this position; it was to the evolving units of that period what the atomic plane is now, the highest point of achievement.  The goal for all was the buddhic plane or the fourth cosmic aether.  Three other planes are the goal now,—the buddhic, atmic and monadic, each time three planes and their eventual synthesis.  In the future solar system the cosmic physical atomic aether (the plane of Adi in the system now) will be the starting point and the three planes to be dominated will be the three lowest cosmic astral planes.  Man starts in where he leaves off, with cosmic physical matter perfected.  His lowest body, therefore, will be the monadic or the body of the second cosmic aether.  This will not be then counted as a principle any more than the threefold lower physical body of present day man is recognised as a principle.
The present solar system will see the surmounting of the three next cosmic physical planes, the fourth, third, and the second aethers, and the coordination of the cosmic etheric body.
