This is a complete fiction, that is, an abstraction that has nothing to do with reality. Someone did a very good job of their mind and came up with an abstract theory that has nothing to do with life.

The core of the "past lives" theory is based on the "piracy" of Awareness. Some people have "memories", but not their own, Life Experience, Realization, but someone else's. Somehow, in a dream or through various rituals, a person manages to see something. Selfishness immediately appropriates what it sees, as it does with everything that a person Realizes.

An analogy can be made. For example, a person from somewhere received a file of a feature film that has not yet been released, or this film has simply ceased to be relevant and forgotten. The selfishness of this person arrogates to itself the rights to the film and passes it off as his work. The same is the case with "past lives" - this is a banal piracy of information property.

Indeed, some people can "remember" episodes of the lives of other people or even animals, which is just an unreasonable phenomenon, like most of the surrounding life phenomena. There is no point in associating such episodes with anything, and apart from increasing the feeling of self-importance, it does nothing to the person.

The universe is one and everything that happens in it is only conditionally divided into objects. Man is just such a separation, but it is temporary. This temporary individuality accumulates Awareness for the Universe. Fragments of a similar, alien Awareness of life are “past lives”. Moreover, scraps of Awareness are also created by living beings, that is, not dead. Psychics can catch this Awareness, as well as dogs when they follow the trail and see everything.

You should know - Awareness is always pure from nature, it does not contain evil for a person. Evil is always associated with the mind, and even with the most frostbitten villain, after death, Awareness is pure, if, of course, it has accumulated in him. Evil, that is, egoism, does not pass on the other side of death, it is exclusively the fate of the living and is in continuous internal dialogue.

Any birth is always a new life, a life from scratch.
