Here is a detailed explanation of what it means for a chain to consist of seven globes, labeled A to G:
Globes A to G: Each chain contains seven globes, labeled A, B, C, D, E, F, and G.
Each Chain consists of seven Globes.
Chains and Globes: Each Scheme evolves through seven Chains, with each Chain comprising seven Globes arranged in pairs that move through different planes of existence (spiritual, intuitional, mental, emotional, and physical).
This name is derived from the fact that a Chain consists of seven Globes, mutually interrelated ; it is a chain of seven links, each link a globe.
The seven Schemes are shown in Diagram I, around the central sun and at any one period of time only one of the rings in each Scheme will be active ; each ring of each of these seven Schemes is composed of seven globes; these are not figured separately but form what we here have drawn as a ring, in order to save space.
In the Scheme to which our Earth belongs, the Chain which preceded our terrene Chain was the third of its series, and its one physical globe, globe D, was the globe which is now our Moon; lifence the third Chain is called the lunar, while the second and first Chains are designated only by numbers; our Earth Chain, or terrene Chain, is the fourth in succession, and has therefore three of its seven globes in physical manifestation, its third globe, C, being what is called the planet Mars, and its fifth globe, E, what is called the planet Mercury.
