“Looking at a single globe we find that during the period of its activity seven root-races of a humanity evolve on it, together with six other non-human kingdoms interdependent on each other.
As these seven kingdoms contain forms at all stages of evolution, as all have higher reaches stretching before them, the evolving forms of one globe pass to another to carry on their growth when the period of activity of the former globe comes to an end, and go on from globe to globe to the end of that round;
they further pursue their course round after round to the close of the seven rounds or manvantaras;
they once again climb onward through manvantara after manvantara till the end of the reincarnations of their planetary chain is reached, when the results of that planetary evolution are gathered up by the planetary Logos.
Needless to say that scarcely anything of this evolution is known to us; only the salient points in the stupendous whole have been indicated by the Teachers.”
