Spirit state?

Do the inhabitants of the other worlds have material bodies like ours and do they pass away like us into their several spirit worlds?

I have told you that in those worlds with which I am acquainted, there is nothing of that which you experience as death. In many cases in your world, death is accompanied with great pain and suffering of both body and mind. But in the worlds referred to, it is far different. 

In these happy worlds, the inhabitants live to a great age—having run their course, they go as it were to sleep and wake up in the spirit world invested with the spirit body. 

It is not, you will perceive, your death, but a translation. All have material bodies and all in due time pass quietly away into the spirit world, which is the great Universe. 

I know of no spirit sphere (as you call it) belonging to one world and not to another. 

Although spirits from worlds outside the Solar System do not generally intermingle with those spirits belonging to it, there is nothing absolutely to prevent them. 

I may illustrate this by directing your attention to that which you see on earth. 

Spread over the surface of the earth, you have many countries in varied forms, sizes and features—these again peopled by different races with their several languages, manners, customs and religions—all differing, yet all belonging to the earth, and as these tribes of men are all drawn to their respective localities by the ties that bind mankind generally, that is, by sympathy in nationality and religion, and so on, it is even so in the spirit state. 

There still prevails a feeling of kinship by which the spirits of one nation are drawn towards those who have gone before who belonged to that nation.

The peoples of the earth have their localities here, as they had while sojourning in the mortal body, but there is nothing to hinder those outside our system intermixing with us anymore than there is anything to prevent natives of one country on earth mingling with those of another.
