The idea of ​ ​ reincarnation is directly an integral part of some religious systems. Moreover, the topic of reincarnation is always associated with the idea of ​ ​ karma. So many books have already been written on these occasions that, it would seem, there is no reason to write another one. However, not everything is so simple. And the fact is that there is still no sufficiently clear justification for the essence (meaning) of reincarnation, just as there is no explanation of the mechanism of action and content of the reincarnation process.
