“Seth material” search engine (Jane Roberts)

Your thoughts are as natural as the cells within your body, and as real. They interact with one another as viruses do. While you are in this reality there is no division between the mental, the spiritual, and the physical. If you think there is, then you do not sufficiently understand the spirituality of the flesh or the physical reality of your thought.

Now: As stated, thoughts are as natural as any portion of the body. They are as much a part of nature as feelings are, but if you set up an arbitrary division — considering thoughts mental as distinguished from the physical — then your body may give a truer reflection of your being than your thoughts do.

When you consider ideas as mental and apart from nature, then you feel separated from nature itself. When you imagine a life after death as unnatural or supernatural then you feel divorced, cut off and bewildered. You must try to understand that there are different kinds of nature within Nature — and a capital for the last one. Your physical life — your human nature — is, in your terms, dependent upon a time when you were not. You must realize that not being in that connotation is quite as natural as physical being. Your existence before and after death is as much a normal phenomenon as your present life.
