Do you guys actually believe this stuff?

To have some decency and reach a shared understanding?

I have provided definitions. Is this not enough?

To clarify I don't mean thoughts I mean stuff like astral bodies, and thought forms attaching to auras.

You seem to agree that there is justification for the existence of thoughts as metaphysical entities. That's a shoe in the door. That opens an entire world of experience that needs to be catalogued. I've already said that emotions are poorly understood and that if you pay attention to these, you will find the metaphysical data you need to begin distinguishing the substance in this metaphysical world of experience. As you do so, certain patterns of interaction emerge and it becomes necessary to use names like "astral body" or refer to the concept of an attaching thought form. I don't like this vague metaphysical vocabulary any more than you do, but right now it is what we have.

Isn't geometry a "non-physical" element of nature?

Yes. All patterns are non-physical, whether they are thoughts that interpret patterns or natural laws that enforce them.
