Are there people without a Soul?

Within the concept of One soul, there are no such.

Just a single Soul they have so deeply hidden that it is almost not visible. And you don't feel it, and you don't feel it.
It would be correct to say even so that we cannot see the Soul as such, maybe she's absolutely not material. But we can see the reaction of the Soul. The reaction of our physics to it. And someone in the future will even say:" we saw the Soul and measured it " rulers. In some measure, for consciousness, for this level - they will be right.
We can appreciate the reaction of our physics, which we accepted for the Soul itself. We can't say we lied, because our physics reacted like that. And "measuring" the Soul, we would measure the response of our devices to it.

So, tn "heartless" is so clogged and blocked with his thin body, using CT single Soul manifests itself in the material world that we cannot see the reaction of their physics on it.

How did it happen?
We consist of vibrations. Everything consists of vibrations of electric current and not only. Next, we've built a lot of instruments and apparatus, CT scans also emit in the different bands. And did not think about how the use of these devices will affect our subtle bodies.

If you take out the massager and starts massaging you well. Your rough body is fine. And well whether different body? Alas, we not thought about this?
Take another example-pills. All of this, too, vibration. So Makar, a person can be, physically, perfectly healthy, but one of the bodies might be almost at the point of death!

Here the root of delusion about soulless.

Yeah their are people without souls. Their called gingers. xD

I think people have souls, but I don't they have a heart. (killers)

Maybe. But even if there isn't you still need to be weary of people. Nobody can be trusted.

well there might be some people without a soul, or rather a very quiet and dark one.
I believe we all have soul, is like the most intimate escence we have
