270, 5. All evil characteristics and their consequent distortions, whether inherited or acquired, reside in the earthly mind. The reason evils and their consequent distortions reside in the earthly mind is that in form, or in image, this mind is an earthly world. The spiritual mind, though, is in form or in image a heaven, and there is no way for evil to find a welcome in heaven. So from birth, this latter mind is not open, only potentially so. The earthly mind derives its form in part from substances of the earthly world, but the spiritual mind derives its form solely from substances of the spiritual world. This latter mind is kept in its wholeness by the Lord so that we can become human. We are actually born animal, but become human.
The earthly mind, with everything in it, turns in spirals from right to left, while the spiritual mind turns in spirals from left to right. So the two minds are turning in opposite directions--a sign that evil is resident in the earthly mind and that on its own, it resists the spiritual mind. Further, turning from right to left is turning downward, toward hell, and turning from left to right moves upward, toward heaven. I have been shown this by the experience that evil spirits cannot turn their bodies from left to right, only from right to left, while good spirits find it hard to turn from right to left and easy to turn from left to right. Their turning follows the flow of the deeper levels of their minds.
