In the case of those who are killed in battle, as in all other cases of violent death, a spirit, during the first few moments, is in a state of bewil… - Allan Kardec

During life, a spirit is held to the body by his semi-material envelope, or perispirit. Death is the destruction of the body only, but not of this second envelope, which separates itself from the body when the play of organic life ceases in the latter. Observation shows us that the separation of the perispirit from the body is not suddenly completed at the moment of death, but is only effected gradually, and more or less slowly in different individuals. In some cases it is effected so quickly that the perispirit is entirely separated from the body within a few hours of the death of the latter but in other cases, and especially in the case of those whose life has been grossly material and sensual, this deliverance is much less rapid, and sometimes takes days, weeks, and even months, for its accomplishment. This delay does not imply the slightest persistence of vitality in the body, nor any possibility of its return to life, but is simply the result of a certain affinity between the body and the spirit which affinity is always more or less tenacious in proportion to the preponderance of materiality in the affections of the spirit during his earthly life.

You often say, 'I have had a strange dream, a frightful dream, without any likeness to reality' You are mistaken in thinking it to be so; for it is often a reminiscence of places and things which you have seen in the past, or a foresight of those which you will see in another existence, or in this one at some future time. The body being torpid, the spirit tries to break his chain, and seeks, in the past or in the future, for the means of doing so.

The line of march of all spirits is always progressive, never retrograde. They raise themselves gradually In the hierarchy of existence they never descend from the rank at which they have once arrived. In the course of their different corporeal existences they may descend in rank as men, but not as spirits. Thus the soul of one who has been at the pinnacle of earthly power may, in a subsequent incarnation, animate the humblest day-labourer, and vice versa ; for the elevation of ranks among men is often In the inverse ratio of that of the moral sentiments. Herod was a king, and Jesus, a carpenter.
