In passing through the gates of the senses, we have left the spiritual world behind. But not everything that our souls developed when we felt ourselves in the company of the beings of the higher hierarchies has been lost to us. We still carry an unconscious remnant with us. Among many other things, this unconscious remnant is also the basis of conscience. This is another way of viewing conscience. The whole of conscience is still inherited from the spiritual world.
