“20. THEIR FATHERS WERE THE SELF-BORN. THE SELF-BORN, THE CHHAYA FROM THE BRILLIANT BODIES OF THE LORDS, THE FATHERS, THE SONS OF TWILIGHT.
The “shadows”, or Chhayas, are called the sons of the “self-born”, as the latter name is applied to all the gods and Beings born through the WILL, whether of Deity or Adept.
21. WHEN THE RACE BECAME OLD, THE OLD WATERS MIXED WITH THE FRESHER WATERS. WHEN THE DROPS BECAME TURBID, THEY VANISHED AND DISAPPEARED, IN THE NEW STREAM, IN THE HOT STREAM OF LIFE. THE OUTER OF THE FIRST BECAME THE INNER OF THE SECOND. THE OLD WING BECAME THE NEW SHADOW, AND THE SHADOW OF THE WING.
The old (primitive) Race merged in the Second Race, and became one with it.
This is the mysterious process of transformation and evolution of mankind. The material of the first forms – shadowy, ethereal, and negative – was drawn or absorbed into, and thus became the complement of the forms of the Second Race.
The first, or parent material was used for the formation of the new being, to form the body and even the inner or lower principles or bodies of the progeny.
When the shadow retires, i.e., when the astral body becomes covered with more solid flesh, man develops a physical body.
The “wing”, or the ethereal form that produced its shadow and image, became the shadow of the astral body and its own progeny.”
H. P. Blavatsky
