Can constructs be created in non-material reality?
In principle, there is no reason why energy cannot be constructed even without the help of the brain, body and language, although such constructs are likely to be different.
If knowledge is a construct, does that mean that it falls off after death, and therefore is only useful during physical life? What knowledge remains after death?
Forms that contribute to the structuring fall off (e.g. a particular language), but not the network that was established with the help of these forms. So, knowledge is not lost even if signifiers may be - only, it is not formulated in the same way as in physical life (it is not bound to specific end points and is also more fluid than when supported by the brain). Such knowledge is not a part of the rings that gradually break apart, but the energy configuration that corresponds to the rings and can be preserved after death. In other words, in the absence of synaptic connections, the implicit aspect of memories remain in the soul, although their specific form may be lost.
How is it that certain information can be preserved after death (at least temporarily), but some can be instantaneously lost following a brain-injury?
Temporary amnesia suggests that memories are not fully lost, otherwise they could not be retrieved. In some cases of brain injures a loss of memory may be even confused with an inability to communicate memories, but this cannot explain everything. A more complex way of looking at this issue is needed. Amnesiacs do not usually forget early memories, but only recent ones, which indicates that the rings are in the process of formation during the physical life, when the soul relies heavily on the brain. So, perhaps, only those memories that are not yet fully integrated are lost (like computer documents that are not saved). It is also possible that a brain injury actively prevents access to memory as long as there is a link between the soul and the brain (direct signals from the rings are weaker than those coming from the brain). Again, this can be compared with using computers. As long as a computer works well, a user relies on its ‘memory'. Suppose, however, that the computer crashes and the user does not have a back-up. As long as s/he is attached to the computer, the effects of the malfunction apply. However, if s/he detaches from the machine, s/he may start to recreate what is lost from shis own more vague, less precise memory that nevertheless may bring about many pieces of information and their relations that can no longer be recovered from the computer.
Does the soul have an I? Is there an identity even after death?
In non-material reality a soul can still retain the rings for awhile, and therefore an I. A soul that loses its rings does not have a projected identity, but it has its unique ‘shape'. This shape is, of course, less permanent and stable, but a soul in any case remains distinct because of its centre (the self) that provides a unique (first person) perspective.
Are all souls in non-material reality good?
There is no reason to believe so, considering that their development can still vary, that there is choice, and that there are different interpretations of what the purpose is and especially how to achieve it. Some interpretations are still necessary in the non-material realm, so even souls can be mistaken and delusional. The Intent may be beyond a dichotomy of ‘good and evil', but souls are not.
Can non-material entities affect the physical world?
Considering that there are beings in non-material reality at different stages of development, the question of whether they can influence the material world cannot be avoided. In the end, all that folklore about spirits, saints, daemons, angels and so on, is perhaps not utterly groundless. What is certain is that they cannot move mountains (or even chairs - the physical world is stronger by far). Yet, there is no reason why they could not operate on the boundaries of natural laws or communicate certain meanings or ideas, providing that there are recipients able to pick up such subtle information. This should not be confused with talking to dead relatives or auto-projections when one's own wishful thinking or fears get externalised (e.g. seeing winged angels or hearing voices forcing the person to do something). Spiritualists (mainly in the 19th century, at the time when the radio and other transmission devices were invented) developed ingenious methods to prove that communication with the deceased is possible. However, even the credible ones are open to different interpretations, so they remain inconclusive. In any case, assuming that an interaction with non-material reality may happen, it should be an exceptional phenomenon for several reasons: it is difficult to penetrate through the barriers of the world structure (those who attempt to establish the contact must open up to an extraordinary extent). The ways of communicating in two realities are different and difficult to make compatible. Also, there is a lack of interest, souls that are able to permanently remain in non-material reality should be aware that heavy interference would go against the Intent. The possibility of some sublime influences (of which source we cannot be conclusive in order to preserve agency) is not excluded though. However, they can never override individual choice. So even if a ‘message' is selected from the noise of the brain and interpreted correctly, it may still be ignored. In any case, such experiences are constructive only if necessary, so they must be rare. Any frequent occurrences or ongoing guidance would be, in fact, contrary to individual development, and therefore should be treated with scepticism.
Can souls die?
Unlike the body, the soul is not susceptible to entropy, so it cannot deteriorate or die in the common sense, ‘naturally' (which would also be an enormous waste). However, souls are only potentially immortal. They can cease to exist as separate units if one of the two fundamental principles, static and dynamic, completely takes over (it is most likely though, that in this case their energy becomes a part of the greater whole). If the static principle becomes so strong as to prevent movement and the exchange of energy, it may lead to the ‘extinguishing' of the soul. If the dynamic principle becomes so strong that the energy cannot remain focused any more, the soul disintegrates, dissolving the self. It is also worth mentioning that individual souls can be assimilated by other souls, which probably has a similar outcome.
Even if an individual soul manages to preserve itself as a whole, is it capable of surviving on its own in non-material reality or must it join other souls?
It does not have to. Souls have intrinsic needs for coherence and development. Whether these needs are satisfied through personal transformation, independent interaction, assimilation, or integration with other energy units may vary from case to case. This is not to say that others are not important. After all, to fulfil the purpose, the unity of souls must be eventually achieved. So, the subject of interaction with others (in material and non-material reality) may be worthwhile consideration.
