A Scheme of evolution passes through seven Chains, and each Chain is made of seven Globes, lettered A to G:
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.
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.
The scheme is built on sevens: seven Schemes, seven Chains, seven Globes, seven Rounds and seven paths.
