Reincarnation is the idea that some people are conscious that their soul that has lived within another organism at a time in the past. Some people believe that their soul can now go on living, but in another body after their current body is dead.
If reincarnation is possible, some or all human beings have a soul that can pass into a different body to keep living.
Reincarnation beliefs differ according to religion. Some do not believe in reincarnation at all and just believe that when the body dies, everything ends. Others believe that people are composed of body, mind and soul to form a single entity. Three different things that when the body dies, are separated and therefore, the soul; most of the energy will move to a different body.
In some cases, the soul has retained part of the energy of the body and mind of the past, to be transmitted to the new organism. In the new body, the mind can remember certain things about the past life of the body that has died, while others only remember a past when they are in a state of hypnosis.
