that we have a scheme of globes starting in the lower mental world,
dipping through the astral into the physical and then rising into the lower
mental through the astral again.

Just as the succession of the globes in a chain constitutes a descent into
matter and an ascent from it again, so do the successive incarnations of a
chain. We have described the condition of affairs in the fourth
incarnation; looking back at the third, we find that that commences not on
the lower level of the mental world but on the higher. Globes 3A and 3G,
then, are both of higher mental matter, while globes 3B and 3F are at the
lower mental level. Globes 3C and 3E belong to the astral world, and only
globe 3D is visible in the physical world. Although this third incarnation
of our chain is long past, the corpse of this physical globe 3D is still
visible to us in the shape of that dead planet the Moon, whence that third
incarnation is usually called the lunar chain.

The fifth incarnation of our chain, which still lies very far in the
future, will correspond to the third. In that, globes 5A and 5G will be
built of higher mental matter, globes 5B and 5F of lower mental, globes 5C
and 5E of astral matter, and only globe 5D will be in the physical world.
This planet 5D is of course not yet in existence.

The other incarnations of the chain follow the same general rule of
gradually decreasing materiality; 2A, 2G, 6A and 6G are all in the
intuitional world; 2B, 2F, 6B and 6F are all in the higher part of the
mental world; 2C, 2E, 6C and 6E are in the lower part of the mental world;
2D and 6D are in the astral world. In the same way 1A, 1G, 7A and 7G belong
to the spiritual world; 1B, IF, 7B and 7F are in the intuitional world; 1C,
1E, 7C and 7E are in the higher part of the mental world; 1D-and 7D are in
the lower part of the mental world.
