Concept: 

“When the Fourth Seal is redeemed

heart and mind can communicate

without restricting each other any longer

In this place, the die is cast

the direction is taken

the intent is fulfilled

This pair opens the only possible path to Heaven

Through Grace received

and consistency restored”

(The Golden Book XII, Meditative Writing)

The Microcosm Inside video shows the rotating operation of the Seal.
