Every religion It has its own characteristics and principles; the dogmas they are different, as are the rituals and commandments that their faithful must fulfill. However, there are certain points that several of them share, and one of them is the reincarnation .
This concept refers to the existence of a essence in the human being who returns again and again to a material support (the body ). This means that, after the death of a person , a part of it comes back to life (the physical world) through reincarnation.
The usual thing is to understand this essence of the individual as the soul (spirit or soul), although it is also possible to believe that what comes back from physical death is Energy or other immaterial dimension.
For him Hinduism , reincarnation is part of the cycle known as karma . This is a kind of wheel or chain in which the actions of the person affect their successive reincarnations until the dharma Enough to end the cycle.
Something similar holds the buddhism , a religion that indicates that only reach the nirvana (a state of enlightenment and pain where there is no suffering) allows the person to free himself from the cycle of reincarnations.
Many scholars say that reincarnation is not possible, but not simply because they do not believe in supernatural issues, but supported by a theory almost as difficult to develop as to refute. In the first place, it is worth mentioning that many of these people claim to wish with all their might to be wrong, since they are not skeptical; However, their more logical side prevents them from ceasing to maintain that reincarnation cannot exist as it is traditionally posed, because it is random for a reincarnated person to live in full only one of their lives.
To understand this position it is necessary to propose a simple example: if, in the present, an individual is in his fourth lifetime and there are still four more to go through, why capricious reason of the universe has full awareness of it, lives it day by day, minute by minute, and not the previous or future? Is it stuck in time? What makes your current identity so special that it occupies your whole mind and does not leave the previous ones more than a tiny possibility of manifesting itself through a dream or a flashback?
This theory, one of the many that opposes the validity of reincarnation, proposes that a reincarnated person should live all his identities at the same time, since each of them could only be aware of itself but could not exist without the others, so that they should all be united although divided. It is a position that tries to doubt the apparent randomness that emerges from believing that the present is everything, especially for someone who claims to have had past lives.
In other words, if there was reincarnation, all the lives of a person should coexist on different temporal planes, all overlapping and enjoying the same importance; All individuals who share soul, both past and future, should be able to ask at the same time if they have inhabited another body before and if they will do it again. The problem that this poses, and the core of the theory in question, is that the same soul could not be in more than one weather both.
In colloquial language, the idea of reincarnation is used to indicate that a subject is very similar , either physically, by personality characteristics or by certain abilities, to another person already deceased. For example: "This singer looks like the reincarnation of John Lennon: he has the same tone of voice", “Many Formula 1 drivers dream of being the reincarnation of Juan Manuel Fangio”.
