"Wabi" represents sadness, and "sabi" represents the fleeting and ephemeral nature of things as they scatter.

In reality, the extinction of the soul occurs everywhere and constantly, and it is a part of the everyday life of this world, and it is something that is both fleeting and sad. If we were to express it, we could call it "wabi-sabi," which is like a fleeting dream in this world.

Sometimes, a part of oneself, which has separated from the group soul and become an individual soul, lives a life, and as a result, a part of that self may be deemed unnecessary by the original group soul and extinguished. As part of the purification of the group soul, a part of the soul is separated and returned to nothingness. Literally, it is an extinction, a return to energy, and by returning to nothingness, all experiences and thoughts disappear.

This generally occurs in about 5% of the aura of the entire soul, and in most cases, there is no need to worry about it. However, separately from that, there are rough people in the afterlife, and such people with a lot of bloodlust (spirits, or humans with bodies) will see any suspicious consciousness and extinguish them. In that case, literally, that evil spirit's consciousness will return to nothingness. It seems that even souls that are not particularly evil but emit an unpleasant atmosphere are often extinguished arbitrarily. In this case, it is not a matter of 5%, but the entire soul that exists as an individual soul may be extinguished.

Memories of living a life, repeating reincarnation, crying, and being sad, or the experiences accumulated through repeated reincarnation, all of that can return to nothingness.

That is a very sad story, like a fleeting dream.

This does not necessarily happen, but unexpectedly, one's soul may be extinguished without intending to.

On the other hand, if one is reincarnated on Earth with a physical body, one is relatively safe because one is protected by the body.

Therefore, the afterlife is a relatively scary and dangerous world, and that is why there is also an aspect of living safely by forming a community with close people without going too far.

Battles between spirits and evil spirits, as depicted in manga, are quite common, but even so, one can live without getting involved in such stories. The world of the afterlife is relatively independent, and there are communities that are fighting evil spirits and communities that are simply living happily, and they rarely interact with each other, and they are often in a situation where they "cannot see" each other because their worlds are too different.

Even so, if there are circumstances and one becomes depressed, they may be seen as evil spirits, and there is a risk that if one carelessly approaches such rough people, they may suddenly be attacked and destroyed.

It is possible to wander around on this earth as a ghost, enjoying it like a trip, but it is difficult to know where such rough people are, and even if they are not visible, they may be behind walls, so enjoying life as a ghost on earth is always dangerous.

It is much safer to be reborn as a human. Of course, there are concerns about money and housing, but compared to the annihilation of the soul, these are relatively minor concerns.

Life with a physical body on earth is relatively lenient from the perspective of annihilation, but the afterlife is quite strict, cruel, and a world with considerable sadness.
