Since any primitive tendencies or derailments that the beings on the spiritual plane have are exposed to their surroundings and cannot thus be hidden from their fellow beings, their transition to the spiritual plane will be a painful one. In my main work I have termed this unpleasant transition to the above-mentioned psychic plane "purgatory". If the human being hates or feels bitter towards a fellow being, or has pangs of conscience and dies or is liberated from its physical existence in this state of mind, this will likewise give rise to an experience of purgatory on the spiritual plane. The whole of this dark state of mind now appears on the spiritual plane as an external condition. And the being cannot get on to the wavelength of any thoughts that are not of the same kind as its own. Here it thus meets only bitter and angry beings in the same state of mind as that in which it finds itself. And as it no longer has the physical organism to sense through, it cannot see the physical sky, the physical sunshine, the beautiful physical landscapes, green forests and flowery meadows or any of the many other divine blessings that Nature uses to enliven the dark soul. Here it thus finds itself in a world of more or less night-black shadows. Here there is no external nature other than that which can be created or imagined by its own sphere of thought and that of like-minded beings. And as long as bitterness or anger dominates, its own ideas, as well as those of like-minded fellow beings, can be but humdrum and bleak. And they cannot possibly come out of this dismal wavelength-condition as long as they feel bitterness or anger towards anyone or anything. But the fact that the beings have thus become spiritually isolated from all mental light makes them feel unhappy as quickly as is possible. And with this feeling the desire for help arises automatically. At the very moment that this feeling or kind of thought arises in the being's psyche, it constitutes a wavelength that the guardian angels can get into contact with; these angels can then liberate the being from the above-mentioned dark thought or this entire dark complex of consciousness. The being can then enter into that state of consciousness or way of experiencing life that constitutes the ultimate ideal existence or culminating happiness that it can grasp. In Livets Bog I have termed this epoch of culminating happiness on the spiritual plane "paradise". Absolutely all existing living beings have such an experience of paradise on the spiritual plane while they are relieved of physical existence, an experience they have until they are born again on the material plane and have a new physical organism. But absolutely not all beings will experience purgatory. Those who live out their terrestrial lives in contact with their innermost perception of life and are not in any kind of mental conflict with other beings, or themselves, will not experience purgatory.
