Pastor R. B. Thieme Jr. coined the term "dynasphere" to refer to Power Systems and it is derived from 2 Greek words:
(gr) "dunamis" meaning power
From Dunamis we get in the English DYNO meaning power in words such as Dynamometer
A dynamometer or dyno for short, is a device for measuring force, torque, or power.
(gr) "sphia" meaning sphere
a subject or area of knowledge; a range or area of activity
the political sphere, the spiritual sphere
Thus Dynasphere is a power sphere. Due to the relative frailty of man and as a result of his purpose for existing being a resolution of the conflict between GOD and Fallen Angels led by Lucifer, in order for man to live and function in this life on this earth every person depends on some aspect of outside power.
Therefore, in order to live on this earth and function in a world ruled by Satan the individual person MUST function within some outside POWER SYSTEM. There are 2 available to him. There are only 2 because man was originally created to resolve the conflict between the revolutionary Lucifer with his followers and GOD so that, in the Garden of Eden, when man was created, God set up a test for man with 2 options to choose from. This was basically a test for Adam, and later his wife, to choose to live under God's Power System or the Power System of Satan. This test involved a prohibition of eating the fruit of the Tree of the Knowledge of Good and Evil, which was the production and policy of the Plan of Satan.
