Presumably not, since you wouldn't have described it as spiritual...

Spiritualism? No.
Dowsing? No.

Corporeal? The best and least misleading answer is No. (There is a pedantic sense in which the answer is Yes, because “anything to do with” is pretty broad and vague.)

Solipsism? No—but the audience awakes from its torpor and there is *some applause, mixed with a little laughter* .

On my Marx-Magnet scale^©, I'd probably put the various isms that have been suggested in the following order, with Idealism/Solipsism/AOTC being fairly close to each other. All three are invented by humans but could in some sense be fact.

Marxism ... Veganism ... Hypnotism ... Spiritualism ... Creationism/Btheism ... Idealism/Solipsism/AOTC ... ... Magnetism

Idea about the nature of the entire universe? Yes! *sustained applause*
To do with logic? No.
Relate to death? The best answer is No, though an indirect argument could be made for Yes.
