When the spiritual mind is open, though, the state of the earthly mind is entirely different. Then the earthly mind is inclined to obey the spiritual mind and to be subservient. The spiritual mind acts on the earthly mind from above or from within; and it moves aside the things there that are reactive and adapts to its purposes the things that are cooperative. So it gradually eliminates any overpowering resistance.
We need to realize that action and reaction are involved in everything in the universe, no matter how large or small, whether alive or lifeless. This yields a balance throughout, which is canceled when action overcomes reaction or vice versa. It is the same for the earthly mind and the spiritual mind. When the earthly mind is acting on the basis of the delights it loves and the fascinations of its thinking (which are intrinsically evil and false), then the reaction of the earthly mind moves aside whatever comes from the spiritual mind and blocks the doors against its entry. As a result, any action is controlled by whatever agrees with the reaction. This is the nature of the action and reaction of the earthly mind, which is the opposite of the action and reaction of the spiritual mind; and this is what causes the closing of the spiritual mind or the reversing of the spiral.
However, if the spiritual mind is open, then the action and reaction of the earthly mind are reversed. The spiritual mind is acting from above or within, and as it does so it is working through whatever in the earthly mind is amenable, whether it comes from within or from the outside. Then it reverses the spiral characteristic of the action and reaction of the earthly mind. This mind has been in opposition to the purposes of the spiritual mind from birth, deriving this by heredity from our parents, as is well known.
This is the nature of that change of state called reformation and regeneration. The state of the earthly mind before its reformation might be compared to a spiral twisted or twisting downward, while after its reformation it might be compared to a spiral twisted or twisting upward. So before our reformation, we are looking down toward hell, while after our reformation we are looking up toward heaven.
