The Genesis, in chapter XIV, Allan Kardec teaches that an intensive and long obsession (strong interdependence between the obsessing and the obsessed) can generate organics injuries through the "problematic" spiritual fluids. "Such fluids act over the perispirit and that, on its turn, reacts over the material organism with which it is in actual molecular contact. (...) if bad fluids were permanent and energetic one they may determine physical disorders. Some diseases do not have any other cause but this (6). Master Lyon, in The Book of the Spirits, questions 481-483, recognizes that an obsessive spiritual influence may cause an epileptic neurological injury and proposes that the obsession curing method may lead the patient to madness. (7) Epilepsy has many relations with natural mechanisms of trials and expiations, in the context of current and former causes of our afflictions. Thus, instead of the epilepsy having an organic cause, the spiritual influence so that it may happen must not be ignored. As Andre Luiz narrates, a case in which during an epileptic convulsion, the obsessing, linking to Peter, followed by a generalized tonic-muscle convulsion, with sphincters relaxation. Guardian Aulus affirms that it is complete obsession or essential epilepsy and analyses that, in physical field, Peter is unconscious, he will not remember the occurrence, but he is alert in spirit, filing the incident and enriching himself. (8) In the sequence of the fact, after praying and passing, there is the disconnection of the disincarnated, the convulsion ends and Peter gets in sound sleep. "With successful obsession curing therapy, it will be possible to end the "possession" attacks, but Peter will suffer the reflexes of the unbalance situation in which he is involved being expressed in softer phenomena of the secondary epilepsy that will arise for some time, before stronger memories of the current struggle until the integral readjustment of the perispirit (conditioned reflex)"(9). This case demonstrates that, although being an obsession, there was no manifestation from the obsessing after the convulsion, certainly because of the pass applied during the convulsion which produced the disconnection of the disincarnated spirit. It is inferred, considering the present exposition, that the epilepsy cases may be caused by obsession, too, as long as there are cases without action from disincarnated spirits and mixed cases. Independently of the case, with or without obsessive involvement, there is the need for the use of medication from the academic medicine, and it is considered obvious that oppression curing therapy is highly efficient, and it must be used as it is recommended in the works of Kardec.
