There are many versions, someone believes that after death, souls go to heaven or hell, someone believes that there is nothing at all if there is no body, someone else believes that souls live forever in heaven, there is an opinion about reincarnation. Since observing the world, we can conclude that "everything is interconnected" - I think reincarnation is the best option. There is nothing in our world that can disappear. I mean disappear completely. For example, water - having fallen as a rain, it will saturate the earth, saturate all living things, but having “worked out” it will not disappear, but having changed its shape, it will go to the sky in a circle and this cycle will continue indefinitely. Plants - they are food for living beings, they are eaten - they change their shape, then the processed plants are fertilizer for new plants … And so on … That is, any something simply changes its shape, it cannot disappear,he has nowhere to disappear, because we live in a closed vessel, there is simply no way out from here.
There was an experiment in which a particle behaves in some conditions like a wave, and in others like a particle. That is, everything that is in the world is a mixture of matter and energy, just like a person, for example. There is a body, it can be fixed on the material level, but there is also a soul - which we cannot see, but it is. Accordingly, when the material shell has worked out its term - where does the energy go? if we talk about human life, we can see that life is a long lesson, in which we receive all the punishments or rewards from the creator not sometime after death, in the hellish cauldron, but right away, here, in this life. It is in this life that a person is responsible for his mistakes, sins, and for good, right deeds. Cause and investigation. Life experience, if you will … Human life includes all imaginable and inconceivable trials,moral and physical pain, which you cannot imagine in a hellish cauldron. And in general - what's the point of being responsible for your mistakes in the next life - if you don't remember? What lesson can you learn from this? Just that life is an unfair shit … Nooo friends, we bear all the responsibility during life … Therefore, corruption priests are not afraid of punishment in hell. Hell and heaven on earth. And they bought themselves this paradise.
From the point of view of nature, nothing exists without a reason. If something is, then it has a purpose. Any thing. And personally, I don't think there is any sense in the other world. What for? Well, that is, if the soul leaves the body, perhaps there is some period of time when it is not with a new body, but is it possible that it is not? Every day someone is born and someone dies, it's just a puzzle. Elderly people are sometimes in a coma before leaving, and pregnant women often lie in preservation, isn't it throwing souls in search of a body? And so I think, can the soul, leaving the old body on the same day in the hospital, find a new one?
